John Jack Bownass (July 27, 1930 – February 10, 2010) was a Canadian ice hockey player who played 80 games in the National Hockey League with the Montreal Canadiens and New York Rangers from 1958 to 1961.

The rest of his career, which lasted from 1950 to 1971, was spent in the minor leagues.

He was born and died in Winnipeg, Manitoba.

[citation needed] The Canadian Amateur Hockey Association established a second Canadian national team in 1967, to increase the available pool of players at the 1968 Winter Olympics, and Father David Bauer recruited Bownass to coach the second team which was based in Ottawa.
