John Murray "Moe" Henderson (born September 5, 1921) is a retired Canadian professional ice hockey player who played 405 games in the National Hockey League. Born in Toronto, Ontario, he played for the Boston Bruins. He is the nephew of Lionel and Charlie Conacher.
He had a brief five game tryout with the Boston Bruins in 1944-45 that led to a steady job with the team for seven seasons until 1952. He was an unspectacular but effective defenceman. In 405 NHL games (all with Boston), Henderson scored 24 goals and 62 assists.
