Robert "Rob" McElhenney (//; born April 14, 1977) is an American actor, director, producer, and screenwriter. He is best known for playing Mac on the FX/FXX comedy series It's Always Sunny in Philadelphia. He is also one of the developers, executive producers, and the creator of the show, which has provided him with writing and directing credits on various episodes.
McElhenney was born in Philadelphia. As a child, he liked to play tennis and racquetball. He attended Saint Joseph's Preparatory School, and in the spring of 2013 he established a scholarship fund with his wife and Sunny co-star Kaitlin Olson.
McElhenney scored his first major role with a small part in The Devil's Own, followed by small parts in A Civil Action, Wonder Boys, and Thirteen Conversations About One Thing, though his roles in The Devil's Own and Wonder Boys were cut out of the final edits. He later had more substantial parts in Latter Days and The Tollbooth, and a small role in the Law & Order episode "Thrill". At the age of 21, a debut script by McElhenney was optioned with writer-director Paul Schrader attached to direct, before the project fell through after one year of edits and rewrites.
Initially based in New York City after his graduation from high school, McElhenney moved to Los Angeles at the age of 22. In 2004, McElhenney was waiting tables between acting jobs when his idea for a sitcom was pitched to many cable networks. After receiving offers from many of the stations, McElhenney chose to sign with FX as they allowed him more creative freedom. McElhenney was contracted as It's Always Sunny's showrunner. He met Glenn Howerton through his agent, and Charlie Day in New York while shooting a horror film. Both Howerton and Day were listed as executive producers.
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. 
Before the first season of It's Always Sunny in Philadelphia went into production, McElhenney hired actress Kaitlin Olson to play the role of Dee Reynolds. He became romantically interested in Olson by "around season 2" of the series, believing her to be the funniest woman in show business. They were married in California on September 27, 2008 .
In 2009, McElhenney and Olson announced their purchase of Skinner's Bar at 226 Market Street in Philadelphia ( 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.). It was renamed Mac's Tavern.
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.
