The Winnipeg Monarchs were a Canadian junior ice hockey team that competed in the Manitoba Junior Hockey League from 1930 to 1978.

The Winnipeg Monarchs junior team was founded in 1930. From 1930 to 1936, they co-existed with the Winnipeg Monarchs senior hockey team. The junior Monarchs won the Memorial Cup as Canadian Junior Hockey Champions three times, in 1935, 1937 and 1946. In 1946, George Robertson scored the winning goal in the seventh game of the 1946 Memorial Cup Final before a sell out crowd at Maple Leaf Gardens in Toronto, Ontario. The Monarchs were also finalists in 1932, losing to Sudbury Wolves in the final, and 1951, losing to the Barrie Flyers.

In addition the three Memorial Cup titles, the team won ten Turnbull Cups as Manitoba Junior Hockey League champions and five Abbott Cups as Western Canadian junior hockey champions. The Monarchs are inducted into the Manitoba Hockey Hall of Fame in the team category four times (1932, 1937, 1946, 1951).

The club changed its name to the Assiniboine Park Monarchs in 1975, but reverted to the original name two years later. A group of Winnipeg businessmen purchased the Monarchs following the 1978 season and relocated it to Fort Garry in south Winnipeg. As part of the move, the team was renamed the Fort Garry Blues. The club has since relocated to Oak Bluff, Manitoba, just outside of Winnipeg, and is currently known as the Winnipeg Blues.
