The World Ski Orienteering Championships (Ski-WOC) is the official event to award the titles of World Champions in ski orienteering.
The World Championships is organized every odd year.
The programme includes Sprint, Middle and Long Distance competitions, and a Relay for both men and women.
This event was called "Short distance" from 1988 to 2000.
In July 2017 it was announced that the IOF Council had decided to redistribute the medals for 2017, following the disqualification of Polina Frolova's results from the World Ski Orienteering Championships 2017 due to violation of anti-doping rules.
