Ryan Lee Stiles (born April 22, 1959) is an American-Canadian actor, comedian, director, and voice actor whose work is often associated with improvisational comedy. He is best known for his improv and co-production work on the American and British versions of Whose Line Is It Anyway? and the role of Lewis Kiniski on The Drew Carey Show.

Stiles was born in Seattle, Washington, the youngest of five children. His father, Sonny, was a fishing plant supervisor. His mother's name is Irene. When he was ten, his Canadian-born parents moved the family to Richmond, British Columbia. At the age of seventeen, he dropped out of his high school, Richmond Secondary, to pursue a career in comedy. He briefly worked in his father's fish-processing plant to earn a living. He then began performing improv with Vancouver TheatreSports League. In 1986, Stiles successfully auditioned for a berth at Toronto's renowned Second City comedy ensemble.
By 1989, Stiles had gained the attention of the producers of the British improvisational comedy show, Whose Line Is It Anyway?. Stiles was a regular on the show until 1998, and the show's short production season allowed him to make numerous television and motion picture appearances in the United States.
