The 1964 New Mexico gubernatorial election took place on November 3, 1964, in order to elect the Governor of New Mexico. Incumbent Democrat Jack M. Campbell ran for reelection to a second term against Republican Merle H. Tucker. Campbell defeated Tucker in a landslide, receiving the largest share of the vote by any New Mexico gubernatorial candidate to that point. Campbell's 60.21% vote share remained the largest ever in the state's history until 2006 when Bill Richardson received 68.82% of the vote. Richardson's 2006 landslide is also the only time since this election that Chaves County and San Juan County have voted for a Democratic gubernatorial candidate and Los Alamos County also did not vote Democratic again until 2006.
