New Mexico (The Land of Enchantment) shares borders with four U.S. states and two Mexican states:
| Direction | Neighbor | Border Length | Notes |
|---|---|---|---|
| North | Colorado | ~320 mi (515 km) | Straight line (37°N parallel); Four Corners at NW tip. |
| Northeast (short) | Oklahoma | ~50 mi (80 km) | Only via the "Oklahoma Panhandle" (Cimarron County). |
| East | Texas | ~500 mi (800 km) | Follows 32°N parallel (mostly); Rio Grande forms southern portion. |
| South | Chihuahua, Mexico | ~300 mi (480 km) | Desert border; crossings: Columbus–Palomas, Santa Teresa–San Jerónimo. |
| Southwest | Sonora, Mexico | ~80 mi (130 km) | Short stretch; crossing: Antelope Wells–El Berrendo (limited hours). |
| West | Arizona | ~390 mi (630 km) | Meridian 32°W; Four Corners at NE tip (only 4-state point in US). |
New Mexico's borders are almost entirely survey lines (parallels/meridians) — a legacy of 19th-century territorial politics.
