The 1983–84 WIHL season was the 38th season of the Western International Hockey League (WIHL), a highly regarded senior ice hockey league that operated in British Columbia, Canada, and the Pacific Northwest United States. The WIHL, which ran from 1946 to 1988, was renowned for its competitive play, often attracting former professional players and serving as a significant pipeline for teams competing for Canada's national senior hockey championship.
During the 1983–84 campaign, the league consisted of several competitive teams from both sides of the Canada-U.S. border, known for their fierce rivalries and passionate fan bases. The season culminated with the Trail Smoke Eaters winning the WIHL President's Cup as league champions. This victory earned them the right to represent British Columbia in the national Allan Cup playdowns.
The Trail Smoke Eaters continued their dominant run through the national playoffs, ultimately capturing the Allan Cup, Canada's national senior ice hockey championship. They defeated the Thunder Bay Twins in the final series, marking a significant triumph for the team and the WIHL, and bringing national recognition to the community of Trail, British Columbia. This achievement underscored the high caliber of hockey played within the WIHL during this era.
