Global StarCraft II League (GSL) is a StarCraft II tournament held in South Korea from 2010 to the present. It has been hosted by afreecaTV since 2016; GOMeXp hosted it from 2010–2015. Blizzard Entertainment was involved in co-producing and co-funding it for much of its history, although their involvement reduced in later years. For the first two years of the tournament, it featured two leagues, Code S (major) and Code A (minor); afterward it ran as a single combined tournament.
