The 1970–71 Mexican Pacific League season was the 13th season in the history of the Mexican Pacific League (LMP). It was contested by eight teams, two more than the previous season. The season was played in two halves, with teams earning points at the end of each half according to their finish. The four teams with the highest cumulative points qualified for the postseason, that were played in a round robin. If the team that finished first in the regular season and the winner of the postseason round-robin were different, a final series would be played to determine the champion.

Two teams joined the league: the Algodoneros de Guasave and the Mayos de Navojoa. The Mayos had originally debuted in 1962, played for five seasons until 1967, and then returned in this season; while the Algodoneros made their debut in the LMP.

The Naranjeros de Hermosillo won their fourth championship, defeating the Cañeros de Los Mochis in the final series 3–1, led by manager Maury Wills. Naranjeros' Héctor Espino won the batting Triple Crown, recording a .348 batting average, 22 home runs and 62 RBI. By winning the LMP title, the Naranjeros became the first Mexican team to participate in the Caribbean Series, doing so in the 1971 tournament.
