The Mexican Pacific League (Spanish: Liga Mexicana del Pacífico, or LMP), officially known as the Liga ARCO Mexicana del Pacífico for sponsorship reasons, is a ten team professional baseball winter league based in Northwestern Mexico.

At the end of the regular season the total number of points are added up from both halves to determine playoff positioning.

In 1945, a group of people led by Teodoro Mariscal established the Liga de la Costa del Pacífico (English: Pacific Coast League).

[6][7] In 1970, the league changed its name to the current Liga Mexicana del Pacífico (English: Mexican Pacific League) and joined the Confederación de Béisbol Profesional del Caribe (English: Caribbean Professional Baseball Confederation), thus participating for the first time in the 1971 Caribbean Series.

[9] Two teams joined the LMP for the 2020 season: Sultanes de Monterrey, that became the first team to play in the two professional baseball leagues in Mexico, and Algodoneros de Guasave, that returned to the Mexican Pacific League after disappearing in 2014.
