Stanley Carl "Bulldog" Jonathan (born September 5, 1955) is a Canadian former ice hockey left winger, most notably for the Boston Bruins of the National Hockey League, for whom he played for parts of eight seasons, and featured in two Stanley Cup Finals (1977, 1978).

[citation needed] Jonathan was adept at knocking in rebounds, and Cherry, his coach at the time, stated that he had the most accurate shot in the league.

Besides his scoring touch, Jonathan was also a capable enforcer, having fought Keith Magnuson, Dave "The Hammer" Schultz, and Andre "Moose" Dupont.

Arguably Jonathan's most famous moment[4] was his savage beating of Pierre Bouchard in a brawl during Game 4 of the 1978 Stanley Cup Finals.

Stan Jonathan was charged with criminal negligence in a hunting accident on the Six Nations reserve that killed Peter Kosid of Hamilton, Ontario, on Sunday, November 11, 2012.
