The Women's Flat Track Derby Association's (WFTDA) West Region was formed in 2006. In 2009, teams from the eastern part of the region were moved into the North Central and South Central Regions.
From 2008, the WFTDA changed from having just two regional tournaments (East and West), to five, made up of teams from four regions: East, North Central, South Central and West.
For 2011, the region was reduced in size, with teams in New Mexico moving to the South Central Region.
WFTDA has now moved away from the Big 5 WFTDA Championships qualification tournament structure, last competed in 2012. Starting with the 2013 WFTDA season, the regions were discontinued in favour of an overall-rankings based system, and a new playoff format was created.
