Thomas Ernest "Moose" Johnson, also known as Ernie Johnson, was a Canadian ice hockey player whose professional career spanned from 1905 to 1931. He was a member of four Stanley Cup winning teams between 1905 and 1910 with the Montreal Wanderers of the Eastern Canada Amateur Hockey Association (ECAHA) and later the National Hockey Association (NHA). He moved west, and switched from left wing to defence, in 1911 to join the newly formed Pacific Coast Hockey Association (PCHA). He spent the following decade playing with the New Westminster Royals, Portland Rosebuds and Victoria Aristocrats where he was named a PCHA first-team all-star eight times and played in the 1916 Stanley Cup Finals with Portland.

The Montreal Wanderers were an amateur, and later professional, ice hockey team based in Montreal. The team played in the Federal Amateur Hockey League (FAHL), the Eastern Canada Amateur Hockey Association (ECAHA), the National Hockey Association (NHA) and briefly the National Hockey League (NHL). The Wanderers were four-time Stanley Cup winners. Prior to the formation of the NHL, the "Redbands" were one of the most successful teams in hockey.
