Mike Barnes is a fictional character from the British Channel 4 soap opera Hollyoaks, played by Tony Hirst. He first appeared on 9 January 2006. In 2010, soap opera magazine Inside Soap reported that the character would leave in late January with love interest Zoe Carpenter (Zoë Lister). This was later confirmed. The character briefly returned in August 2016 and again in March 2017, where his youngest daughter Amy Barnes (Ashley Slanina-Davies) was killed off in a "whodunit" storyline. He returned again in September 2017 giving evidence against Ste Hay (Kieron Richardson) during Amy's murder trial.
