United Soccer League

The United Soccer League (USL) is an organizer of various professional and amateur soccer leagues in the United States league system. It currently organizes its Championship, League One, and League Two for men, its Super League and W League for women, and the USL Academy and USL Youth for youth players. It also organizes the USL Cup, a league cup competition for its professional men's clubs.
The USL began in 1986 as a men's indoor soccer minor league, before branching out into outdoor soccer in 1989. After rebranding as the United States Interregional Soccer League (USISL), it commenced a women's outdoor league (the W-League) and split its men's outdoor league into two pro and one amateur league over the course of 1995–96. Its top pro flight would merge with the American Professional Soccer League to become the A-League in 1997 – a decision influenced by the advent of Major League Soccer (MLS). Its indoor league folded in 1998. The USISL adopted the name United Soccer Leagues in 1999.
In 2011, a number of USL clubs broke away to form the North American Soccer League, necessitating the merger of its two pro leagues into one. The USL also took ownership of the Major Indoor Soccer League, though it and the W-League would fold by 2015. Despite these setbacks, the USL experienced growth in the late 2010s, leading to a split of the professional leagues back into two in 2019. It also revived the W League and established a pro women's league between 2022 and 2024. A third men's pro league, tenatively named USL Division One, is currently being planned for a 2027–28 debut.
The Rochester Rhinos men's team and Pali Blues women's team are the most successful clubs in the USL, having won four championships each in its top flights. Two USL clubs, the Rochester Rhinos and the Richmond Kickers, have won the men's U.S. Open Cup. Seven men's clubs that played in the USL – the Seattle Sounders, Portland Timbers, Vancouver Whitecaps, Montreal Impact, Orlando City SC, FC Cincinnati, and Nashville SC – are now MLS franchises.
The United Soccer League (USL) traces its roots to 1985 when Francisco Marcos founded the Southwest Indoor Soccer League. Initially intended as a minor indoor league associated with the Major Indoor Soccer League, it began with five teams owned by operators of indoor soccer arenas in the Southwest United States. By 1986, Marcos' own team, the Austin Sockadillos, joined the league, expanding it to six teams.
In 1989, the league shifted its focus beyond semi-professional indoor soccer. A press release from that year revealed ambitions to align with the United States Soccer Federation (USSF)'s plan to professionalize soccer in the lead-up to the 1994 FIFA World Cup. The league aimed to become part of a structured, three-tiered system envisioned by the USSF.
By 1990, the league began with their first outdoor soccer competitions, and rebranded as the Sunbelt Independent Soccer League, reflecting broader ambitions. Throughout the 1990s, the league underwent significant changes. This included splitting out an amateur Premier League in 1995 (renamed to the Premier Development League (PDL) in 1997), and the launch of their first attempt at a women's league. A merger with the American Professional Soccer League was completed in 1997 to form the USISL A-League (later named the USL First Division), solidifying its position in the U.S. soccer pyramid.
In 2009, several USL First Division clubs expressed dissatisfaction with the league's leadership and structure, leading to a significant split. These clubs formed a breakaway competition called the North American Soccer League (NASL), which aimed to operate as a separate second division under the USSF. This division sparked disputes over sanctioning rights between the USL and the NASL. In response, the USSF organized a temporary combined league in 2010 before officially sanctioning the NASL as a separate entity.
In 2010, the USL unified its First Division and Second Division under the name USL Pro to consolidate its professional competitions, and moved down to the third division. In 2013, USL Pro and Major League Soccer (MLS) entered a partnership to integrate their competitions, enhancing player development and strengthening the league's professional status. The W-League folded in 2015. Second division sanctioning was once again granted by USSF in 2017. In 2019, the professional league rebranded to USL Championship, the PDL rebranded as USL League Two, and a new division three league named USL League One was launched.
In recent years, the USL has expanded its reach significantly in the women's game. It reintroduced the W League in 2022 to support women's development and launched the USL Super League in 2024 as a Division I professional women's league alongside the National Women's Soccer League.
On February 13, 2025, the USL announced plans to launch a Division I league in 2027 that would exist apart from MLS, pending USSF approval. It also restated its desire to eventually introduce a promotion and relegation system like most other global soccer leagues. On March 19, 2025, USL announced that that club owners had overwhelmingly passed a proposal to adopt promotion and relegation throughout all of the organization's professional leagues, including the upcoming Division I league. No timeline for the start of the process had been determined.
The USL operates three divisions within the U.S. soccer pyramid for men's professional and developmental teams:
The USL has a history of organizing leagues and competitions that have since evolved or ceased operations:
These competitions show the evolution of the USL from its origins as an indoor soccer league to a modern, multi-tiered system supporting professional and developmental soccer across North America.
