Samuel Jonathan McMillan

Sammy J, born Samuel Jonathan McMillan in Mornington, Victoria, on 2 July 1983, is an Australian musical comedian, satirist, writer and radio presenter. He embraces a variety of media in his comedy, including video and self-composed music, and frequently collaborates with Australian puppet comedian Randy Feltface. His stage name is an old high school nickname and a contraction of his full name, first used publicly during a 1999 performance on Hey Hey It's Saturday's "Red Faces" segment.

McMillan studied law at the University of Melbourne for two and a half years before dropping out, later graduating with a Bachelor of Arts in Media and Communications in 2006. In 2006 he won the Best Newcomer award at the Melbourne International Comedy Festival for his debut solo show, Sammy J's 55 Minute National Tour. His 2017 show Hero Complex, about his childhood love of The Phantom, won Best Comedy at the Melbourne Fringe Festival and earned a nomination for Best Comedy Performer at the 2017 Helpmann Awards. In 2008 he collaborated with puppeteer Heath McIvor on the adult musical Sammy J in the Forest of Dreams, which won The Age Critics Award, and in 2010 the pair created Ricketts Lane, which won the Barry Award.

He has appeared on Australian television shows including Spicks and Specks, Good News Week and Talkin' 'Bout Your Generation, and in 2018 inherited the Clarke and Dawe time slot on ABC television. From January 2020 he hosted ABC Radio Melbourne's Breakfast show, leaving in December 2024 after five years. In May 2020 his song "Pink Clouds" won the comedy category of the International Songwriting Competition, and in April 2018 he released his first book, The Long Class Goodnight.
