The New Brunswick Senior Hockey League operated under the authority of the Maritimes Amateur Hockey Association (MAHA) and the Canadian Amateur Hockey Association (CAHA). Its teams were eligible for the Allan Cup.
It operated for only 2 seasons - 1952-53 & 1953-54. It then changed its name to the Atlantic Coast Senior Hockey League, which itself only lasted until the end of the 1955-1956 season.
