Mike Smith (born August 27, 1972, Thorburn, Nova Scotia) is a Canadian actor, who plays Bubbles on Trailer Park Boys.

Smith showed early signs of musical talent, after learning how to play the guitar at age seven. He earned a degree in English from St. Francis Xavier University in Antigonish, Nova Scotia. Before joining the show, he was a guitarist in the rock band Sandbox, and signed a record deal with EMI in Canada, and Nettwerk in the United States. Sandbox released two albums with EMI and Nettwerk, entitled "Bionic" and "A Murder in the Glee Club." Sandbox was nominated for a Juno Award, East Coast Music Awards, and a Casby Award.

Smith has mixed sound for such films as The Weight of Water and Serendipity.

He had been a long-time friend of Trailer Park Boys director Mike Clattenburg, and met Robb Wells (Ricky), and John Paul Tremblay (Julian) while sound mixing on the original TPB feature. Mike introduced Mike Clattenburg to a character that he had made up, once called Darren, and it was written into the show. Bubbles was never intended to be a main character, but the more outrageous he behaved, the more audiences loved him. Bubbles then became one of the three main protagonists, having established that he knew them from school back in the late 70s to high school in the late 80s.

Smith made a cameo appearance as Bubbles in Snow's 2002 music video Legal, but his swearing remains bleeped.[1]

He is also a hockey player, starring for the Pictou County Weeks of the Nova Scotia Midget AAA Hockey League when he was in high school.

He opened his own bar "Bubbles' Mansion", located in downtown Halifax, Nova Scotia.

He has appeared in character as Bubbles at several Guns N Roses 2006 Canadian tour dates.

He is presently engaged to actress Nichole Hiltz.
