The International Women's Flat Track Derby Association Championships ("WFTDA Championships" or "Champs" for short) are the leading competition for roller derby leagues. The Championships are organised by the Women's Flat Track Derby Association (WFTDA). They originated in 2006 as the National WFTDA Championship. The "Dust Devil" tournament was contested in front of several thousand fans in Tucson, Arizona. This was the first multi-league flat track roller derby tournament. In 2017, the final game of the tournament will be broadcast live on ESPN2.
