Seth Rogen (born April 15, 1982) is a Canadian actor, comedian and writer.

Rogen began his career doing standup comedy for four years during his teens, coming in second place in the Vancouver Amateur Comedy Contest when he was sixteen. After moving to Los Angeles, Rogen landed supporting roles in Freaks and Geeks and Undeclared (the latter of which also hired Rogen as a staff writer).

After landing a job as a staff writer on the final season of Da Ali G Show, for which he and the other writers received an Emmy nomination, Rogen was guided by director Judd Apatow toward a film career. Rogen was cast in a major supporting role, and credited as a co-producer, in Apatow’s directorial debut The 40-Year-Old Virgin. After receiving critical praise for that performance, Universal Pictures agreed to cast Rogen as the lead in Apatow’s next directorial feature, Knocked Up.

Rogen has appeared in the films Donnie Darko, You, Me, and Dupree and Fanboys, in addition to the Apatow-produced comedies Anchorman: The Legend of Ron Burgundy and Superbad (a semi-autobiographical comedy Rogen originally intended to headline years ago, co-written by Rogen and Evan Goldberg). Rogen also wrote the screenplay for another comedy which Apatow helped co-produce, Owen Wilson's Drillbit Taylor.

Attended Point Grey Secondary School in Vancouver, British Columbia.

Son of Mark Rogen.

His parents met each other in Israel.
