David Stephen Forbes (born November 16, 1948) is a retired Canadian professional ice hockey player.

Signed as a free agent in 1973 by the Boston Bruins, Forbes made an impact as a defensive-minded forward as he helped guide the Bruins to the finals in 1974 during his rookie season, and to the finals in 1977. Forbes played four seasons with Boston until he was claimed by the Washington Capitals in the Waiver Draft prior to the 1977-78 season. After playing one season with the Capitals, he was released after only playing two games during the 1978-79 season and signed to play for the Cincinnati Stingers of the World Hockey Association.
