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 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 2016–17 season, it is currently contested by thirteen teams - seven from the Czech Republic and six from Slovakia.^[1] After Austria's win in its only appearance, Slovakia dominated the following six seasons, while the Czech Republic has won the next four editions. Iuventa Michalovce is the most successful team in the competition with eight titles, followed by Slavia Prague and Slovan Duslo Šaľa with two.
