Robert McElhenney III (/ˈmækəlhɛni/ MAK-əl-hen-ee; born April 14, 1977), also known professionally as Rob Mac, is an American actor, screenwriter, producer, director, and businessman. He is best known for his role as Mac on the FX/FXX comedy series It's Always Sunny in Philadelphia (2005–present), a show he created and co-developed with Charlie Day and Glenn Howerton and on which he continues to serve as an executive producer and writer. He is also known for playing Ian Grimm on the Apple TV+ comedy series Mythic Quest (2020–2025), which he co-created with Day and Megan Ganz as executive producers.
