Tyler Christopher (born October 3, 1983 in Chilliwack, British Columbia) is a former Canadian sprinter who specialized in 400 metres.

The following year he competed in 400 metres at the World Championships in Helsinki and won a bronze medal, setting a new national record of 44.44 seconds.

Christopher's return to the World Championships in 2007 saw him finish sixth in the 400 m. At the 2007 Pan American Games in Rio de Janeiro, Brazil, he won the silver medal in 45.05 s behind Chris Brown of the Bahamas.

At the 2008 Beijing Olympics Christopher ran a disappointing 45.67 s, finishing fifth in his heat and not qualifying for the semi-finals.

In an interview with CBC reporter Elliot Friedman after the race Christopher attributed his poor performance to the flu, which had prevented him from training in the days prior to the qualifying event.
