Alan William "Al" Opsahl (September 27, 1924 – July 19, 1990) was an American ice hockey defenseman who competed in ice hockey at the 1948 Winter Olympics which took place in St. Moritz, Switzerland.
Opsahl was a member of the Amateur Hockey Association (AHA) and the co-captain of the American ice hockey team which played eight games at the 1948 Winter Olympics. Although the US secured a fourth-place finish, their official standing was stripped from the records due to a dispute between the United States Olympic Committee (USOC), the Ligue Internationale de Hockey sur Glace (LIHG), and the Swiss organizing committee.
