The WFTDA Western Regional Tournament or WFTDA West Region Playoffs was one of four roller derby qualifying tournaments for the WFTDA Championships. The Tournament was organised by the Women's Flat Track Derby Association (WFTDA). Full WFTDA members in the Western Region members were eligible for ranking, and the top ten leagues would qualify for the Western Regional Tournament, with the top three finalists qualifying for the Championships. Together, the four qualifying tournaments and Championships were termed the "Big 5". Starting with the 2013 WFTDA season, WFTDA's regions were discontinued in favor of an overall-rankings based system, and a new playoff format was created.
