James Norman "Norm, Dutch" Gainor (April 10, 1904[1] – January 16, 1962) was a Canadian ice hockey professional forward.

Gainor was most notable for playing on the Boston Bruins' 1928 "Dynamite Line" with Cooney Weiland and Dit Clapper, one of the earliest "named" forward lines in National Hockey League (NHL) history.

Gainor started his NHL career with the Boston Bruins, later playing for the Ottawa Senators, New York Rangers and Montreal Maroons.

He was a member of two Stanley Cup-winning teams in his career, once with Boston in 1929 and again with the Maroons in 1935.
