The Men's Roller Derby Association (MRDA) is the international governing body of men's flat track roller derby. Originally founded in 2007 under the name Men's Derby Coalition, MRDA promotes the sport of roller derby by sharing resources and knowledge gained through our experience as skaters, business owners and organization leaders.The guiding principles of MRDA are to foster the development of sustainable roller derby leagues, to cultivate positive sportsmanship on and off the track, and to enhance the derby community. MRDA provides new leagues with direction and encouragement while we offer strategic benefits to member leagues. All MRDA member leagues have a say in the organization's operating policies and its goals for the upcoming year. MRDA maintains standards for rules, safety, and gameplay for local, regional and international competitions.All member leagues are skater owned and operated, and agree to comply with MRDA's operating policies.
