The 1920 New Mexico gubernatorial election was held on November 2, 1920.
Incumbent Republican Governor Octaviano Ambrosio Larrazolo was defeated for renomination. Republican candidate Merritt C. Mechem defeated Democratic nominee Richard H. Hanna with 51.26% of the vote. Otero County and Union County both backed a Republican gubernatorial candidate for the first time, but would not do so again until 1950 and 1938, respectively. This was also the last gubernatorial election until 1950 in which Grant County voted for a Republican.
