Nationella Damhockeyligan (lit. 'National Women's Hockey League') or NDHL is the second-highest women's ice hockey league in Sweden. It was previously known as the Damettan or Damettan i ishockey during 2015 to 2021, and Division 1 during 2007 to 2015. The league engages in active promotion and relegation with the top-tier Swedish Women's Hockey League (SDHL) and the third-tier Damtvåan.
Beginning with the first official women's ice hockey Swedish Championship in 1988, the Division 1 served as the premier league for women's ice hockey and the winner of its playoffs was named Swedish Champion. During the 2007–08 season, the best Division 1 teams qualified for a newly created premier league, the Riksserien (renamed SDHL in 2016), at which point Division 1 was reconfigured as the second-tier league.
