The Canadian Peace Congress was a pacifist group founded in 1949 by James Gareth Endicott. The CPC was the Canadian affiliate of the World Peace Council and a leading player in the peace movement in Canada, particularly in the 1950s and 1960s. The CPC was active in the nuclear disarmament and anti-imperialist movements such as the movement against the Vietnam War and promoted the concept of peaceful co-existence between the Communist bloc and the Western bloc.

The CPC was perceived as being close to the Labour-Progressive Party and its successor the Communist Party of Canada though Endicott, himself, was not a party member. Endicott remained the CPC's president until 1971 when, according to his biography, he was pressured to resign by the leadership of the Communist Party for his pro-China views during the Sino-Soviet split.

The Congress disbanded in 1990. During the 1980s it was displaced by the much larger Canadian Peace Alliance (founded in 1985) which was seen as more mainstream as opposed to the CPC which was seen as alinged with the Soviet Union.
