The High-A West is a six-team Minor League Baseball league that began operating in the Pacific Northwest United States and Western Canada in 2021. Along with the High-A Central and High-A East, it is one of three leagues playing at the High-A level, which is three grades below Major League Baseball (MLB). The league was created in 2021 in conjunction with MLB's reorganization of the minor leagues. The league is made up entirely of former members of the Class A Short Season Northwest League.
