The Cosmopolitan Soccer League is a regional soccer league consisting of semi-pro and amateur teams based in and around New York City. Established in 1923, it is one of the oldest soccer leagues in the United States and has contributed greatly to the nation's soccer history. The Cosmopolitan Soccer League plays a traditional international schedule with competition beginning the second weekend of September and running through June, with a winter break from late December to early March. During the winter months, the league runs an indoor tournament due to New York's cold climate.
