The United Premier Soccer League (UPSL) is an amateur soccer league in the United States, established in 2011. It operates in the fourth tier of the U.S. soccer pyramid and has grown significantly, now hosting over 400 teams across the U.S., Canada, and Mexico. The league runs two seasons annually—Spring and Fall—and features a promotion and relegation system within its divisions. Teams from the UPSL are also eligible to compete in the U.S. Open Cup, a historic tournament where amateur and professional teams face off. It provides opportunities for aspiring players and clubs to showcase their talent and potentially advance to higher levels.
