Michael C. Scully (born October 2, 1956) is an American television writer and producer. He is known for his work as executive producer and showrunner of the animated sitcom The Simpsons from 1997 to 2001. Scully grew up in West Springfield, Massachusetts, and long had an interest in writing. He was an underachiever at school and dropped out of college, going on to work in a series of jobs. Eventually, in 1986, he moved to Los Angeles where he worked as a stand-up comic and wrote for Yakov Smirnoff.

Scully went on to write for several television sitcoms before 1993, when he was hired to write for The Simpsons. There, he wrote twelve episodes, including "Lisa on Ice" and "Team Homer", and served as showrunner from seasons 9 to 12. Scully won three Primetime Emmy Awards for his work on the series, with many publications praising his episodes, but others criticizing his tenure as a period of decline in the show's quality. Scully still works on the show and also co-wrote and co-produced 2007's The Simpsons Movie.

More recently, Scully co-created The Pitts, The Boy Who Lost His Schoolbag and Complete Savages as well as working on Everybody Loves Raymond and Parks and Recreation. He co-developed the short-lived animated television version of Napoleon Dynamite, as well as co-creating Duncanville with his wife, Julie Thacker, and comedian Amy Poehler.
