Rogen was born and raised in Vancouver, British Columbia to Sandy, a social worker, and Mark Rogen, who works for non-profit organizations and as an assistant director of a Workmen's Circle.[1][2] He has described his parents, who met at an Israeli kibbutz, as "radical Jewish socialists".[2] He has one older sister, Danya, who is a social worker. Rogen attended a Talmud Torah school and Point Grey Secondary School, incorporating many of his classmates into his writing. He was also known for the stand-up comedy he performed at Camp Miriam, a Habonim Dror camp.[1] Rogen got his start in show business at age 13 after signing up for a comedy class. With his trademark deadpan humour, he placed second in the Vancouver Amateur Comedy Contest at 16, then headed south of the border to continue stand-up and acting.
