List of battles fought in New Mexico

This list of battles fought in New Mexico is an incomplete list of military and other armed confrontations that have occurred within the boundaries of the modern US State of New Mexico since European contact. The region was part of the Viceroyalty of New Spain from 1535 to 1682, New France from 1682 to 1762, Kingdom of Spain from 1762 to 1800, French First Republic 1800 to 1803, and Mexico from 1803-1848. Portions of New Mexico were under the administrative control of the Republic of Texas from 1836 to 1846. Full administrative control of New Mexico was established on February 2, 1848 with the signing of the Treaty of Guadalupe Hidalgo which ended the Mexican–American War.

The Mexican-American War, American Civil War, and Plains Indian Wars all directly affected the region during westward expansion.
