The Northwest League is a Minor League Baseball league that operates in the Northwestern United States and Western Canada. A Class A Short Season league for most of its history, the league was promoted to High-A as part of Major League Baseball's 2021 reorganization of the minor leagues. The league operated as the High-A West in 2021, then resumed its original moniker in 2022.
