The 2006 New Mexico gubernatorial election was a race for the Governor of New Mexico held on November 7, 2006. Incumbent Democratic Governor Bill Richardson was running for re-election. He faced Republican John Dendahl in the general election and won by a landslide. As of 2024, this was the last time a male candidate was elected Governor of New Mexico.

The scale of Richardson's lopsided victory was nearly unprecedented in the traditionally competitive state. Richardson's 68.82% share of the vote is the highest achieved by any gubernatorial candidate in the state by a wide margin, beating the previous record of 60.21% set in 1964. Richardson came within six votes of sweeping every county the state, a feat that has never been achieved in any gubernatorial (or presidential) election in the state.
