Robert Dale "Rob" McElhenney (//; born April 14, 1977) is an American actor, director, producer, and screenwriter. He is best known for playing Mac on the FX comedy series It's Always Sunny in Philadelphia. He is a creator, developer, and executive producer of the show, which has also provided him with writing and directing credits on various episodes. In July 2015, it was confirmed that Rob would be directing the upcoming Minecraft movie for Mojang after being spotted at Mojangs convention, Minecon.
McElhenney was born in Philadelphia, Pennsylvania.  As a child, he liked to play tennis and racquetball. He attended St. Joseph's Preparatory School and excelled in his studies, particularly math and science.
McElhenney made his film debut with a small part in Alan J. Pakula's The Devil's Own, followed by small parts in A Civil Action, Wonder Boys, and Thirteen Conversations About One Thing. He later had more substantial parts in Latter Days and The Tollbooth, and a small role in the Law & Order episode "Thrill".
In 2004, McElhenney was still waiting tables between acting assignments when his manager and agent pitched his idea for a sitcom to FX, which was warmly received. McElhenney claims that 50 weeks of each year are consumed by acting, producing, and writing for the show, but he did find time to appear in the third season of Lost in the episode "Not in Portland". This was a result of McElhenney meeting Lost co-creator and executive producer Damon Lindelof, who is a fan of It's Always Sunny in Philadelphia. McElhenney continued the role in Lost, featured again in the sixth season for a single episode. Rob is a fan of Game of Thrones and was thrilled that the series' writers asked to write an episode of It's Always Sunny in Philadelphia. He and his co-producers accepted the offer.  On July 21st, 2015, he was confirmed by Mojang as the director of the upcoming Minecraft movie.
McElhenney married his It's Always Sunny in Philadelphia co-star, Kaitlin Olson, in California on September 27, 2008. In 2009, the couple announced their purchase of Skinner's Bar at 226 Market Street in Philadelphia ( ). It was renamed Mac's Tavern. They had their first child, Axel Lee McElhenney, on September 1, 2010. Olson went into labor at a Philadelphia Phillies game. The couple's second son, Leo Grey McElhenney, was born on April 5, 2012.
In preparation for the seventh season of It's Always Sunny in Philadelphia, McElhenney put on 50 lbs of extra weight and let his beard grow out to give extra humor to his character and add a new comedic direction for the season. His co-star Charlie Day described the weight gain as "disgusting" and that the rest of the cast were "a little on the fence about it for his own personal health and safety". McElhenney subsequently lost 23 lbs in a month after the season was finished filming. He lost more later in the year to film the next season.
