Sergeant Marc D. Léger (March 26 1973-April 17 2002) was a Canadian soldier killed in Afghanistan when two U.S. planes dropped an unauthorized laser-guided bomb on the 3rd Battalion of the Princess Patricia's Canadian Light Infantry. The infantry was participating in a training exercise which involved firing anti-tank and machine-gun rounds.

Léger was originally from Lancaster, Ontario. He was 29 and had served in the Canadian Army for 9 years when he died.

His widow, Marley Léger, created a memorial fund in his name to help with restoration in Bosnia, where her husband had served on a peace keeping mission in 2000. On May 10 2003, she opened a restored community centre in the Vrbica village in Livno Valley there which was rebuilt using money from the fund and the Canadian International Development Agency.
