"Right By My Side" is a song by American recording artist, Nicki Minaj, taken from her second studio album, Pink Friday: Roman Reloaded (2012). The song also features additional vocals from R&B artist Chris Brown. "Right by My Side" was written by Ester Dean, Minaj, and Safaree Samuels, while production was handled by Andrew "Pop" Wansel and Oak. On March 27, 2012, "Right by My Side" was released as the third official single from the album to Rhythmic and Urban radio in the U.S.
Musically, "Right by My Side" is an upbeat R&Bballad infused with elements of pop and hip hop. It has been heavily compared to several other songs, including Jordin Sparks "No Air", in which Brown was featured on, Rihanna's "You da One", and even Minaj's own track "Right Thru Me". Critics noted the songs "bubbly" persona, as well as its high quality production. "Right by My Side" was received positively by music critics, though Brown's inclusion on the song caused mild controversy. Minaj performed the song live for the first time on 106 & Park on April 3, 2012. Minaj also performed the single during her surprise appearance at the Nokia Lumia 900 launch in Times Square.
In an interview with Ryan Seacrest, Minaj said about the song: "Toward the end of the album I wanted something more melodic that I could give to urban radio and that pop radio could enjoy as well. I actually had the beats for like 3 months just sitting in my computer and then I said, 'You know what? This sounds like a summer, R&B classic joint' and I just could not hear anyone else on it but Chris Brown. So I reached out to Ester Dean and I said, 'Could you write something for Chris Brown?' Because she's amazing with writing and especially for his voice, she has a great skill to write for his tone and she sent it, I fell in love with it, you know 'cause everybody has had a relationship like this song is talking about, [so] I went in and I wrote my rap, cause I'm rapping and singing in the song, and when we put it all together and let people hear it, everybody was like, this is a hit, release this ASAP."
"Right by My Side" is an upbeat take on a downtempoR&Bballad. The song is also heavily influenced by pop, and features a "glossy", "bubbly" production. Some critics found similarities between "Right by My Side" and other songs by fellow female R&B artists, specifically Jordin Sparks and Rihanna. Both Justin Ray of Billboard, Andrew Hampp of Billboard, and Robbie Daw of Idolator found the lyrics and themes similar to those of Sparks 2008 single "No Air" which also featured Brown, Andrew Unterberger of Popdust felt the song was a more successful version of Rihanna's "You da One".
"Right by My Side" received mostly positive reviews from critics, who complimented the song's fun atmosphere, while others criticized it for being too "generic". Andrew Hampp of Billboard said the song sounded "sonically similar to Jordin Sparks and Brown's 'No Air'", and complimented Minaj for letting her guard down. Jesal Padania of Rap Reviews criticized the song for being weak, as well as commenting on the choice to release it as a single, saying "I guess they choose star power over star quality." Andrew Martin of Prefix Magazine was disappointed that the song featured almost no rapping, and called it another "soft-as-hell ballad". In a separate article, Justin Ray of Billboard gave a positive review of the song, and praised Brown's verse. Upon being released, "Right by My Side" entered the US Hot R&B/Hip-Hop Songs chart at 52 in its opening week, and peaked at 21 on the chart.
