Alexander Wuttunee Decoteau (November 19, 1887 – October 30, 1917), was a Cree Canadian track and field athlete, police officer and soldier.

Decoteau joined the Canadian Expeditionary Force in April 1915 and died on October 30, 1917, during the Second Battle of Passchendaele.

[3] His father, who fought alongside Plains Cree Chief Poundmaker at Battle of Cut Knife in 1885, was an employee of the Indian Department when he was murdered in 1891.

[6][7] His sister Emily and Latta, a business man and one-time Edmonton alderman, had married in 1899 and Decoteau initially lived with the couple upon his arrival to the city.

[5][12] Influenced by his father's involvement with the North-West Rebellion in 1885, Decoteau enlisted in the Canadian Expeditionary Force in April 1916.

[4] At an event in Salisbury, King George V awarded Decoteau his personal gold pocket watch as congratulations for winning a 5-mile (8.0 km) race.

[5][6] A common, but unsubstantiated, account of his death suggests that the German sniper stole the pocket watch that had been awarded by the King and that it was later recovered by his comrades, who ensured it was returned to his mother Dora.

[10] Recognition of Decoteau's accomplishments is credited to the work of Edmonton police officer Sam Donaghey.
