Minnesota Roller Derby (MNRD) is a flat track roller derby league based in Saint Paul, Minnesota, in the United States. Founded in August 2004 as Minnesota RollerGirls by the Donnelly sisters, MNRD was one of the first 30 members of the Women's Flat Track Derby Association (WFTDA) by early 2006. Today the league has over 80 skaters playing on four home teams as well as their All-Star team, which has qualified for WFTDA Playoffs every year since its inception.
