Tristan Walker (born May 16, 1991, in Calgary, Alberta) is a Canadian luger who has competed since 2008.

He competed in both the Doubles race and the Team Relay (which made its Olympic appearance in 2014).

He and his teammate Justin Snith missed the podium in the doubles event by just five-one hundredths (0.05) of a second for the best-ever Olympic result by a Canadian sled in the event.

They joined Alex Gough and Samuel Edney for the Mixed team event and had another Olympic fourth-place finish.
