Women Handball International League (WHIL), also known as Czech-Slovak Interliga or for sponsorships reasons MOL Liga, is a supranational championship created in 2002 that serves as the highest women's handball league in the Czech Republic and Slovakia. Following the end of the championship the four best-placed teams from each country play separate play-offs to determine the national champions. The inaugural edition was also contested (and won) by Hypo Niederösterreich from Austria.

The number of teams in the WHIL has ranged from eleven in 2005 and 2009 to fourteen in 2011. As of the 2024–25 season, it is currently contested by twelve teams – nine from the Czech Republic and three from Slovakia. After Austria's win in its only appearance, Slovakia dominated the following six seasons, while the Czech Republic has won the next four editions.
