Mirinda Carfrae (born 26 March 1981) is an Australian professional triathlete and an Ironman Triathlon world champion.

[1] She went on to represent Australia at the Junior and U23 level, winning a silver medal at the 2003 ITU U23 World Championships.

[7] Carfrae's first attempt at longer distances was at the Lake Tinaroo Half Ironman in September 2002, where she finished in second place behind Rebekah Keat, setting a new run course record of 1:21:20.

[10] This win entitled Carfrae to race at the full Ironman World Championships at Kona, but she deferred her entry to 2009, when she felt she was ready for the longer distance.

In 2015, she started the Ironman World Championship race at Kona, but withdrew from the bike leg due to pain from injuries sustained in a collision with a car earlier that week.
