The Swedish Women's Hockey League (Swedish: Svenska damhockeyligan), abbreviated SDHL, is the elite league for women's ice hockey in Sweden. It was established in 2007 as the Riksserien by the Swedish Ice Hockey Association and was renamed prior to the 2016–17 season. The league has ten teams and employs a system of promotion and relegation with the Nationella Damhockeyligan (NDHL). The unexpected withdrawal of Göteborg HC after playing only thirteen games of the 2022–23 season caused the number of teams to decrease to nine for the remainder of that season.
