Eugene Levy, (born December 17, 1946) is a Canadian actor, comedian, producer, director, and writer. He is the only actor to have appeared in all eight of the American Pie films, in his role as Noah Levenstein. He often plays nerdy, unconventional figures, with his humour often deriving from his excessive explanations of matters and the way in which he deals with sticky situations. Levy is a regular collaborator of actor-director Christopher Guest, appearing in and co-writing four of his films, commencing with Waiting for Guffman (1997).

Levy received the Governor General's Performing Arts Award, Canada's highest honour in the performing arts, in 2008. He was appointed to the Order of Canada on June 30, 2011.
