Triathlon is one of the sports at the quadrennial Commonwealth Games competition. It was first granted Commonwealth Games sport status in 2002, and has been held in each edition since, except in Delhi 2010 Games due to the lack of suitable venue for the swimming leg in Delhi. Until 2022, it was a core sport which had to be included in each competition's sporting programme. Para-triathlon was first included as an optional sport in the Gold Coast 2018 games. Triathlon will not be contested at the 2026 Commonwealth Games in Glasgow, Scotland.
