Stuart Ostlund is a Canadian former ice hockey player. He won a national championship with Michigan Tech in the United States before embarking on a brief professional career.

Ostlund debuted for Michigan Tech in 1974 and joined the team just in time for its 3rd championship run. Ostlund averages a point per game during his freshman season and assisted on two goals in the championship game.^[1] His sophomore season saw Ostlund take on a major role with the team and double his point total. He finished in the top 10 in the national and combined with Mike Zuke and George Lyle to form one of the most devastating offensive units in college hockey. Unfortunately, the team came one win shy of repeating their championship, losing to Minnesota in the final.^[2] That summer, Ostlund was selected in both the NHL and WHA drafts. After Zuke and Lyle left MTU, Ostlund's point totals dropped back to about a point per game and he saw less success with Michigan Tech but still finished out his four years in Houghton.

Ostlund turned pro in 1978 and had a tremendous first season. He produced at well over a point per game pace with the Fort Wayne Komets and helping the club reach the league semifinals. Despite the success, he was demoted to the CHL the following year and was able to post only modest numbers with the Dallas Black Hawks. After starting the year with Dallas, he left the team and travelled to Finland, ending the year with SaiPa and then retiring as a player.
