The Winnipeg Shamrocks were a senior team.

They played in the Western Canada Association in 1906-07.

The Shamrocks were tossed from the league after losing their first two games. The other 2 teams - the Winnipeg Winnipegs and the Winnipeg Victorias - voted the Shamrocks out in part because of low attendance.

A professional team by the same name played in the Manitoba Professional Hockey League for the 1908–09 MPHL season finishing tied for first place.
