Mike Doyle (born September 16, 1972) is an American actor, screenwriter, director and producer. He is best known for his recurring roles in the television series Law & Order: Special Victims Unit, playing Forensics Tech Ryan O'Halloran, and Oz, playing Adam Guenzel.
It was on the set of Oz that Doyle met George Morfogen, whom he would cast in Shiner, a short film written, produced and directed by Doyle that debuted at the 2006 Tribeca Film Festival. Doyle also wrote and produced the 2003 limited-release film Cutter.
Doyle played Lt. Cmdr. Tom Palatonio in the 2005 action film Phantom Below, which is notable for having been released in multiple versions under multiple names which included or excluded gay content depending on the edit (the gay-themed edit was released under the title Tides of War). Also in 2005, he plays a gay coffee barista named Andy in 29th and Gay.
On June 2, 2009, The New York Times published an article about Doyle and his tendency to die on screen during his acting roles.
