The 2012 ITU World Triathlon Series was a series of eight World Championship Triathlon events that culminated in a Grand Final held in Auckland, New Zealand in October 2012.

[1] The World Triathlon Series (WTS) visited Sydney, San Diego, Madrid, Kitzbühel, Hamburg, London, Stockholm, and Auckland.

The series took place during the 2012 Summer Olympic year, with many countries using the results of select series races to determine which athletes would qualify to represent their nation in triathlon at the 2012 Summer Olympics.

The stop in Stockholm also served as the location for the 2012 ITU Team Triathlon World Championships.

Elite-level competitors were crowned champions in Auckland based on the final WTS point standings.
