William (Billy) Martin Boucher (Born November 10, 1899 in Ottawa, Ontario – Died November 10, 1958) was a Canadian professional Ice Hockey player.
The Ottawa native spent four years in the local senior league with the Ottawa Munitions club beginning in 1916-17. After playing in the NOHA for Iroquois Falls Papermakers in 1920-21, Boucher made his NHL debut with the Canadiens.
Boucher played in the National Hockey League for the Montreal Canadiens, Boston Bruins and New York Americans. He also played for the New Haven Eagles and Bronx Tigers of the Canadian-American Hockey League.
Boucher signed with the Montreal Canadiens on December 13, 1921, and scored 17 goals in his rookie season. Boucher scored 24 goals in 24 games in his second season. In his third season, 1923–24 Boucher was placed on a line with rookie Howie Morenz and Aurele Joliat in a high-scoring trio. Boucher led the Canadiens in scoring, and was runner-up in the league scoring honors. The team defeated defending champion Ottawa in the NHA playoffs and the Calgary Tigers in the Stanley Cup Final.
The Canadiens would win their second Stanley Cup in team history, and the first as an official NHL franchise.
The Montreal Forum opened on November 29, 1924, with the Toronto St. Pats as guests for the inaugural match. The Canadiens came out on the winning end of the 7-1 game and Billy Boucher had the honor of scoring the first goal at the new venue and finished the night with the first hat trick ever scored at the Forum.
In the 1926–27 season, Boucher was traded to the Boston Bruins for Carson Cooper with both teams holding right of recall, January 17, 1927.
Players returned to original teams, May 22, 1927. Boucher was then traded to the New York Americans for cash on October 17, 1927, where he would finish his NHL career.
Boucher would continue to play Hockey for the New Haven Eagles from 1928 to 1931, the Bronx Tigers for the 1931-32 season and then coached the Quebec Granites for the 1932-33 season.
