The IIHF European Women's Champions Cup or EWCC was an annual women's ice hockey club tournament, contested by the national women's ice hockey champions from several European ice hockey playing nations. The event was established and organized by the International Ice Hockey Federation (IIHF). The competition format included two group phases followed by a final round. Each phase was played as a round robin in groups of four teams each.
 The competition was created by the IIHF in 2004, at the same time as a similar competition for men's hockey teams. The first winner was AIK IF of the Swedish Division I. This Swedish club team then won the following three tournaments. From 2009 onward, the IIHF European Women's Champions Cup was won by teams from the Russian Women's Hockey League, with the exception of the 2010–11 tournament, which was won by Ilves Tampere of the Finnish Naisten Liiga.
 At its zenith, national champion teams from twenty different countries participated in the qualification round and/or second round of the EWCC. However, only teams from Czechia, Finland, Germany, Kazakhstan, Russia, Sweden, or Switzerland ever qualified for the final round of a tournament.
