Kara Zor-El was sent to Earth from Krypton as a 13-year-old by her parents Zor-El and Alura. Krypton was exploding, and Kara's parents sent Kara in a spacecraft to Earth after her cousin. Kara was meant to protect her infant cousin Kal-El, but her spacecraft was knocked off course and forced into the Phantom Zone, where it stayed for 24 years. By the time the spacecraft crash landed on Earth, Kal-El had grown up and become Superman. The series begins eleven years later when the now 24-year-old Kara is learning to embrace her powers and has adopted the superheroic alias "Supergirl".
In the first season, Kara is forced to reveal her powers, and becomes National City's protector. Kara discovers that hundreds of the criminals her mother imprisoned are hiding on Earth, including her aunt Astra and Astra's husband Non. Kara works with her adoptive sister Alex Danvers to fight these criminals, alongside the Green Martian J'onn J'onzz, her cousin's friend James Olsen, and tech genius Winn Schott.
In the second season, Kara and her allies deal with feuds between Earth's native populace and extraterrestrial community, and investigate the shadowy organization Project Cadmus, masterminded by Lillian Luthor, mother of Lex Luthor. At the same time, Kara befriends Lillian's stepdaughter Lena Luthor, the new CEO of LuthorCorp, and struggles with romantic feelings for recent Earth arrival Mon-El, a princely survivor from Krypton's neighboring planet Daxam whose parents wish to reclaim him. James becomes the masked streetfighting vigilante Guardian; Alex begins dating Maggie Sawyer; and J'onn befriends a younger Martian, M'gann, from the White Martian race that killed his people.
In the third season, Kara struggles with the loss of Mon-El after he is forced to leave Earth. When Mon-El returns, he reveals that he has time-traveled to the 31st century and founded the Legion, alongside marrying Imra Ardeen. J'onn discovers his father M'yrnn J'onzz is alive and Alex deals with her heartbreak after breaking up with Maggie. Kara and Alex's new friend, Samantha Arias, is unknowingly another Kryptonian survivor, and begins a transformation from a loving single mother into the world-killing weapon known as Reign, who serves a coven headed by Selena.
In the fourth season, Kara deals with a new wave of anti-extraterrestrial prejudice secretly instigated by Lex Luthor from prison, forcing her to fight for the civil and political rights of aliens. Ben Lockwood, a former college professor who suffered a series of personal tragedies at the hands of extraterrestrials, forms a human-first group called the Children of Liberty to end all aliens. Meanwhile, in the nation of Kasnia, a clone of Kara dubbed "Red Daughter" is trained by its military to fight Supergirl at Lex's request. Kara and Alex rival with the DEO's new addition, Col. Lauren Haley, who was sent to monitor the DEO's progress under Alex's direction. Col. Haley and the President try to force Supergirl to reveal her identity, and clash with her and Alex when she refuses.

Kara worked as Cat Grant's assistant at CatCo. Benoist expressed her excitement over portraying the character, and being able to "[tell] a story about a human being really realizing their potential and their strength".

While working at the Daily Planet, James received the Pulitzer Prize for taking the first photograph of Superman. In the second season, James becomes Guardian. He also becomes the acting CEO of CatCo after Cat Grant leaves the company.

Kara's human adoptive sister. She is a scientist and government agent who serves as Hank Henshaw's right-hand at the DEO. Having been extensively trained in combat by Henshaw, Alex in turn provides rigorous training to Kara in order to decrease her over-reliance on her powers. She and Kara grow suspicious of the DEO upon learning that their missing father was forced to work there in order to protect Kara, but Alex ultimately learns that Henshaw is really the Martian survivor J'onn J'onzz in disguise, whom her late father had rescued before his and the real Henshaw's apparent deaths. In season two, Alex learns that her father is alive and searches for him. She also meets and befriends police detective Maggie Sawyer and begins to develop feelings for her, forcing Alex to confront her sexuality. Jordan Mazarati and Olivia Nikkanen portray a young Alex. At the end of season three, Alex becomes the new director of the DEO.

However, at the end of "For the Girl Who Has Everything", Winn has accepted that it is best that they remain as best friends, and in "Solitude", he begins seeing Cat Grant's new assistant, who is also Kara's rival; Siobhan Smythe, who is subsequently fired by Cat and who, in "Worlds Finest", becomes a supernatural metahuman supervillain called Silver Banshee. In the series, he is the son of Toyman. Cat nicknames him Toyman Junior after she finds out. In season two, Winn left CatCo to work at the DEO as a desk agent.

The head of the DEO who takes Hank Henshaw's likeness after Henshaw is killed in Peru while hunting J'onn. J'onn takes Henshaw's likeness in order to reform the DEO from within as well as to watch over Alex and Kara. The evolution of Henshaw was discussed during the filming of the pilot, with the executive producers jokingly saying that Harewood would be a good actor to play the Martian Manhunter in a potential television series, to which DC Comics' Geoff Johns asked why it could not be done in Supergirl. Harewood reflected that he had difficulty "find[ing] an angle to play Hank Henshaw" in the pilot, and became excited when he was told about the change to his character's backstory. Harewood also recurred in the series as the real Hank Henshaw, who became Cyborg Superman.

Cat investigates and reveals that Supergirl is Superman's cousin, which then causes Kara to become a target for some of Superman's rogues gallery. Cat also serves as a mentor to Kara, dispensing advice about being a woman in a man's world. In the episode "Hostile Takeover", she suspects that Kara is Supergirl. In the second episode of season two, Cat announces she is taking a leave of absence from CatCo, leaving James to run the company in her stead.

By September 2014, Warner Bros. Television was looking to create a television series centered around Supergirl. Executive producers for the series include Greg Berlanti (also a creator/producer for Arrow and The Flash), Ali Adler, who are both writing the script, and Berlanti Productions' Sarah Schechter. DC Comics' Geoff Johns is also expected to be part of the project. Titles under consideration for the series included Super and Girl. Berlanti confirmed the show shortly after, and stated it was in development and had yet to be pitched to networks. Berlanti's take on the character was based on the actress Ginger Rogers, who he felt "had to do everything Fred Astaire did but backward and in heels"; this comparison "really resonated" with executive producer Sarah Schechter. On September 20, it was announced that CBS had landed Supergirl with a series commitment, with an expected premiere in 2015 of the 2015–16 television season. In January 2015, CBS Entertainment Chairman Nina Tassler revealed the show would be a procedural, saying, "There will be [crime] cases, but what [executive producers] Ali Adler and Greg Berlanti pitched was a real series arc for her. The beauty of it is now with shows like The Good Wife and Madam Secretary, you can have serialized story elements woven into a case of the week. She's a crime solver, so she's going to have to solve a crime."
In January 2015, it was announced by The Hollywood Reporter that Melissa Benoist would star as Supergirl. Benoist later revealed that auditioning for the part "was a long, drawn-out, three-month process"; she was the first actress looked at for the role, although Claire Holt and Gemma Atkinson were also considered. In March 2015, Blake Neely, composer for Arrow and The Flash, revealed he would be composing for Supergirl. The show was officially picked up to series on May 6, 2015. It was originally set to premiere in November 2015, before being moved up to October 26, 2015. The pilot episode was screened at San Diego Comic-Con International 2015 on July 8 and 11, 2015. In July 2015, Adler spoke on how much influence Superman would have on the show, saying, "Our prototype is the way the president is seen on Veep. It's certainly [inspired by] so much of what Julia Louis-Dreyfus' character goes through. Ultimately, this is a show about Supergirl and we really want to see it through her lens." On November 30, 2015, CBS ordered an additional seven episodes of Supergirl, for a full season of 20 episodes.
On May 12, 2016, Warner Bros. Television announced that the series had been renewed for a second season of 22 episodes and would move to The CW. The season debuted in October 2016. With the move of the production to Vancouver, it was unclear if Calista Flockhart would remain with the series, as her original contract stipulated that she work near her home in Los Angeles. The CW president Mark Pedowitz said Flockhart wanted to remain with the series and that "We're in ongoing discussions... we're happy to have her in [in whatever capacity] works out." Flockhart ultimately reached a deal to be recurring in the second season, with the production flying her to Vancouver every few weeks to film material.
On January 8, 2017, The CW renewed the series for a third season, which debuted on October 9, 2017. The third season saw Jessica Queller and Robert Rovner become the series' executive producers and co-showrunners along with Kreisberg until his firing, following Adler's departure; Adler will remain an executive consultant for the series. Both Queller and Rovner joined Supergirl midway through the first season as co-executive producer and consulting producer, respectively, with Rovner promoted to executive producer ahead of the second season.
On April 2, 2018, The CW renewed the series for a fourth season, which premiered on October 14, 2018. On January 31, 2019, The CW renewed the series for a fifth season. The fifth season premiered on October 6, 2019. On January 7, 2020, the CW renewed the series for a sixth season.
The costume for Supergirl was created by Colleen Atwood, who also designed the costumes for Arrow and The Flash. Benoist stated that she is aware of the costume worn by Kara in more modern depictions of in the comics, and expressed that the "micro-mini hemline" of the skirt in the version created by Michael Turner could be "a little daunting ... but that's good. I like being pushed." Promotional photos of Benoist wearing Atwood's design were released on March 6, 2015. Atwood indicated that she wanted to "embrace the past ... but more importantly, thrust her into the street-style action hero of today." Atwood later revealed details about the costume such as the cape being fastened to an undersuit so as not to pull the costume and that the fabric used was Eurojersey. The reveal of the Martian Manhunter costume in "Human For a Day" was created through visual effects, though a physical version was created to appear in later episodes, with it proving to be one of the most challenging costumes for the costume team.
Reception of the Supergirl costume upon its reveal was mixed. Entertainment Weekly's Natalie Abrams commented that the new look of the costume looks and feels different in a good way. The new costume avoids exposing the character's midriff, as it does in the Michael Turner version of the costume from the comics, as well as having Benoist wear stockings underneath the skirt with over-the-knee boots. Abrams compared the texture of the costume to that worn by Henry Cavill as Superman in Man of Steel, as well as the positioning of the cape on the suit, and the decision to do away with the bright blue and red color scheme. Andrew Dyce, from Screen Rant, found the new costume to perfectly balance itself between classic nostalgia and modernism. The Washington Post noted that Atwood's design was successful, praising her ability to take "cartoon-y tints" and moving them to darker tones.
E! Online was less impressed with the design, negatively comparing it to a "cheap Halloween costume", with washed out colors, and not buying into the "gritty, 'street style'" look Atwood was intending. TV Guide questioned Atwood's design, and noted that although the promotional image has Benoist trying to appear as a powerful hero, the thigh-high boots and pleated skirt comes across as a "model advertising a moderately-priced Halloween costume".
The suit was redesigned in season five to include pants rather than the traditional skirt.
In February 2015, it was announced that Andrew Kreisberg, co-creator of Arrow and The Flash, had joined the series as a writer and executive producer; and Arrow / The Flash and Smallville alum Glen Winter was announced to be directing the pilot. Principal photography for the pilot took place from March 4 to March 29, 2015. Filming locations included the Warner Bros. lot, where Lois and Clark was shot. Each episode cost approximately $3 million to broadcast, which is one of the highest license fees ever for a first year show.
The second season was filmed in Vancouver, rather than Los Angeles where the first season was shot. This was done to reduce the high production costs of the series, one of the issues that made CBS wary to renew the series on their network. Filming for the third season began in Vancouver on July 6, 2017, and ended on April 28, 2018.

Critics' top ten lists
In November 2014, Berlanti expressed interest in Supergirl existing in the Arrowverse, the same universe as his other series Arrow and The Flash, and in January 2015, The CW president Mark Pedowitz revealed that he was also open to a crossover between the series and networks (due to Berlanti executive producing all three and The CW being co-owned by CBS). However, CBS Entertainment chair Nina Tassler stated that month that "those two shows are on a different network. So I think we'll keep Supergirl to ourselves for a while." In August 2015, Tassler revealed that while there were no plans at the time to do crossover storylines, the three series would have crossover promotions.
Pedowitz regretted passing on the series when presented it in mid-2014, saying, "We hadn't launched The Flash yet, we weren't ready to take on another DC property. In hindsight we probably should've gone that direction...Sometimes you lose great shows." In January 2016, during the Television Critics Association press tour, he said that The CW was still interested in a crossover with Supergirl if the producers could find a way to do it, and Berlanti added that while no official conversations had taken place, internal ones had concerning how a crossover would work. He also noted that for a crossover to happen during Supergirl's first season, it would have to be figured out "in the next month or so". Glenn Geller, Tassler's successor at CBS, then stated on the matter, "I have to be really careful what I say here. Watch and wait and see what happens."
On February 3, 2016, it was announced that Grant Gustin, who appears as Barry Allen / Flash on The Flash, would appear in the eighteenth episode of the first season, "Worlds Finest". While no plot details on the episodes were released at the time, Ross A. Lincoln of Deadline Hollywood noted that "the in-universe reason" for the crossover was due to Barry's ability to travel to various dimensions, thus implying that Supergirl exists on an alternate Earth to Arrow and The Flash in a multiverse. The Flash episode "Welcome to Earth-2" confirmed this, showing an image of Benoist as Supergirl during a sequence where characters travel through that multiverse. The earth that the series inhabits is Earth-38 in the Arrowverse multiverse, and has been informally referred to as "Earth-CBS" by Marc Guggenheim, one of the creators of Arrow.
During the second season, Supergirl appears in "Invasion!", a crossover episode of The Flash, Arrow and Legends of Tomorrow, when she's recruited by Barry Allen and Cisco Ramon at the end of "Medusa" to help fight off an invasion by the Dominators. Supergirl and The Flash also featured in a musical crossover, featuring several covers of existing songs along with two original numbers. Similar to "Invasion!", the crossover begins at the end of the Supergirl episode "Star-Crossed" and primarily takes place during The Flash episode "Duet", featuring the Music Meister as the antagonist who puts both The Flash and Supergirl in a shared hallucination. After "Invasion!", Guggenheim felt "If there's an appetite for it from the fans and from the network," the crossover next year could be "a proper four-part crossover."
At the 2017 Paleyfest event, Kreisberg reiterated the creative team's intention to do a full four-way crossover the following year. At San Diego Comic Con 2017, it was confirmed that another four-way crossover would take place, with Supergirl playing a larger role than the previous season. The four-way crossover event, titled "Crisis on Earth-X", took place on November 27 and 28, 2017, across Supergirl and Arrow (on the first night) and The Flash and Legends of Tomorrow (on the second night).
In May 2018, Arrow star Stephen Amell announced at The CW upfronts that the next Arrowverse crossover would feature Batwoman and Gotham City. The crossover, titled "Elseworlds", aired in December 2018, ahead of a potential 2019 solo series for the character. Supergirl was confirmed to have a participating episode in August, which closed out the three-part crossover, trading nights with The Flash just for the event. Therefore, the show's participating episode aired on Tuesday, December 11. The end of "Elseworlds" teased the next crossover event, "Crisis on Infinite Earths". Supergirl's episode opened the five-part crossover on December 8, 2019, with the final two installments airing on January 14, 2020. At the end of the event, the new Earth-Prime was formed, which saw Earth-38 merged with the former Earth-1 and Black Lightning's earth, creating a fictional universe where all of the CW series exist together.
In October 2019, The CW and Warner Bros. Television announced development on a spin-off series titled Superman & Lois, with Tyler Hoechlin and Elizabeth Tulloch reprising their roles as Clark Kent / Superman and Lois Lane. Todd Helbing was set to write the series and would serve as an executive producer alongside Greg Berlanti, Sarah Schechter and Geoff Johns. In January 2020, Superman & Lois was ordered to series.
In July 2015, a four-page preview comic entitled Sister Act, written by Ali Adler, Greg Berlanti and Andrew Kreisberg was released digitally online, and then a day later in the September 2015 issue of TV Guide.
Beginning in January 2016, DC Comics launched a 13-issue, bi-weekly digital comic, Adventures of Supergirl. Written by Sterling Gates and drawn by a rotating team of artist including Bengal, Jonboy Meyers, Emanuela Lupacchino, and Emma Vieceli, the comic, while not directly tying into the show, tells stories set in the universe of the show. The digital series was collected in print as a six-issue series published twice a month from May to July 2016, and as a complete graphic novel in September of that year.
In November 2017, Abrams Books began publishing a new trilogy of Supergirl novels, written by Jo Whittemore, aimed at middle-grade readers in tandem with a similar trilogy of The Flash novels. The first, Supergirl: Age of Atlantis, was released on November 7, 2017, and features Supergirl dealing with a surge of new powered people in National City, as well as a mysterious humanoid sea creature captured by the DEO who is seemingly attracted by the new superpowered people. A sequel, Supergirl: Curse of the Ancients, was released on May 1, 2018, with a third novel, titled Supergirl: Master of Illusion, released on January 8, 2019.
A guidebook for the series, published by Abrams, was released on March 12, 2019. Supergirl: The Secret Files of Kara Danvers: The Ultimate Guide to the Hit TV Show features "detailed profiles on characters and super powers, a heroes and villains gallery, episode guide, and more" from the first three seasons of the series.
