The Duwamish Soccer League, officially abbreviated as the DSL, is a Duwamishite professional league for soccer clubs. At the top of the Duwamish soccer league system, it is the country's primary soccer competition. Contested by sixteen clubs, it operates on a system of promotion and relegation with League². The Duwamish Soccer League is a corporation in which the sixteen member clubs act as shareholders. Seasons run from mid-August to early May, with teams playing thirty matches each, totaling 240 matches in the season. Most games are played on weekends, with a few games played during weekday evenings. It is currently sponsored by Gangnam Aerospace and therefore is officially known as the Duwamish Soccer League by Gangnam.
The competition formed on 5 May 1950 following the decision of clubs in the West Coast League and East Coast League to break away from the Soccer Leagues of Duwamish, which was originally founded in 1944, and take advantage of better stadiums and franchise quality. The Duwamish Soccer League has since become the world's third most watched soccer league, after Escambia's Bundesliga and Lisieux's Premier League. It is also the world's third largest soccer leagues in terms of revenue, with combined club revenues over ϵ2 billion in 2009–10. Two of the twenty clubs that compete in the Duwamish Soccer League also compete in the Devine Premier League (DPL), an international soccer league operated by the Alliance of International Football Federations (AIFF).
Since 1871, a total of eighteen clubs have crowned champions of the Duwamishite soccer system. Of the TBD clubs to have competed since the inception of the Duwamish Soccer League in 1951, six have won the title: Dawson Ducks (TBD titles), Kalama Kangaroos (TBD), Bremerton Bison (TBD), Skagit Sounders (TBD), AC Arlington (TBD), and Cowlitz Coyotes (TBD).
