The Professional Rapid Online Chess League (PRO Chess League and abbreviated PCL) was an online rapid chess league operated by Chess.com. It was preceded by the United States Chess League, which announced in 2016 that it would be renamed, reformatted, and opened to cities from around the world, and moved to the website chess.com. It was discontinued in 2024.
In its inaugural season, the PCL comprised 48 teams, whose members included some of the highest-rated chess players in the world, including the reigning world champion Magnus Carlsen, and other elite players including Maxime Vachier-Lagrave, Hikaru Nakamura, and Wesley So plus over 100 other grandmasters. The 48 teams represent cities in five continents.
