Sam McMillan (born 2 July 1983) is an Australian musical comedian and writer who performs under the stage name Sammy J. He embraces a variety of media in his comedy, including the use of video and self-composed music. He has released three CD compilations of his comic songs, "The Burden of Popularity", "Sammy J - Live?" and "Sticky Digits", with his latest one "Skinny Man, Modern World" bringing it to 4. He has performed at comedy festivals in Australia and Britain and has appeared on various Australian television shows.

He currently performs with Heath McIvor (aka Randy, a purple puppet) as the duo Sammy J & Randy.

McMillan studied law at the University of Melbourne for two and a half years, where he also directed and appeared in the Melbourne Law Comedy Revue. He says he was more interested in writing jokes than studying, and halfway through the course decided to drop out. He subsequently completed a media degree and began to pursue a full-time comedy career.

He performs under the stage name Sammy J, a condensation of his full name, Samuel Jonathan McMillan. According to McMillan, his stage name originated as a high school nickname which he says he gave to himself "when I was trying to manufacture a bit of popularity... My family and friends were reluctant to adopt it but I pushed and pushed, using it at every opportunity, and eventually started using it on stage."
