The Thunder Bay Hockey League was a multi-classification ice hockey league based in Thunder Bay, Ontario.
Founded in 1980, the TBHL lasted for two years. The league only had four teams, a Senior team, an Intermediate team, a Junior "A" team, and a CIAU University team. In 1982, the Sr. Twins and the CIAU Lakehead Nor'Westers went their own ways as the Intermediate Blazers folded. The league, built around the remaining Jr. A Kings was reformed with two more teams, both Jr. B, and operated for two more seasons as the Thunder Bay Junior Hockey League.
