The 1958 Allan Cup was the Canadian Amateur Hockey Association (CAHA) senior ice hockey championship for the 1957–58 senior "A" season. The event was hosted by the Kelowna Packers and Kelowna and Kamloops, British Columbia. The 1958 playoff marked the 50th time that the Allan Cup has been awarded.

The Belleville McFarlands, of the Ontario Hockey Association, defeated the Kelowna Packers to win the Allan Cup, also earning the right represent Canada at the following year's 1959 Ice Hockey World Championships, where they would win Canada's 18th world title.

Intermediate teams

In August 1957, Alberta Amateur Hockey Association president Art Potter appealed to the CAHA to allow the Allan Cup competition to be opened up to intermediate level teams strengthened by additional players from their local regions. He wanted to see more branches of the CAHA able to enter competitive teams, rather than only the senior teams in Ontario and British Columbia. The 1958 Allan Cup was the first where the CAHA allowed intermediate level teams outside of Ontario and British Columbia to add to their rosters, limited to six players each, to enter a competitive team for the national playoffs.^[1]
