Allan McLean "Scotty" Davidson (March 6, 1891 – June 16, 1915) was a Canadian ice hockey player and soldier.

Davidson turned professional with the Toronto Blueshirts in 1912 and was among the National Hockey Association's leading scorers the following two seasons.

Upon the outbreak of the First World War in 1914, Davidson volunteered with the Canadian Expeditionary Force; he was the first professional hockey player to do so.

[3] Davidson made his professional debut with Toronto in their season-opening loss to the Montreal Canadiens,[10] and finished his rookie season with 19 goals in 20 games, second on the team behind Frank Nighbor.

The Blueshirts named him team captain for the 1913–14 season, and he responded by finishing in the top ten in NHA goals with 23 and second in assists with 13.

[14] When the First World War broke out in 1914, Davidson was the first professional hockey player to volunteer with the Canadian Expeditionary Force, enlisting on September 22, 1914 with the 14th Regiment.

[16] While on his way to England on the steamer SS Cassandra Davidson showed off his athletic skills by winning the championship in a big boxing tournament held on the boat, defeating David Carson of Kingston, Ontario in the finals.

[18] He once rescued a wounded officer while fighting in France, and one account of his death asserts that he was shot in the back and killed while attempting to carry an injured soldier to safety.

[19] Contemporary reports suggested that had Davidson lived through the attack, he may have been awarded the Distinguished Conduct Medal or even the Victoria Cross.

[20] By the time he left hockey to fight in the war, Davidson was considered one of the top all-around players in the NHA.
