The Battle of Glorieta Pass, fought from March 26-28, 1862, in the northern New Mexico Territory, was the decisive battle of the New Mexico Campaign during the American Civil War. Dubbed the "Gettysburg of the West" (a term that "serves the novelist better than the historian") by some authors, it was intended as the decisive blow by Confederate forces to break the Union possession of the West along the base of the Rocky Mountains. It was fought at Glorieta Pass in the Sangre de Cristo Mountains in what is now New Mexico, and was an important event in the history of the New Mexico Territory in the American Civil War.

There was a skirmish on March 26 between advance elements from each army, with the main battle occurring on March 28. Although the Confederates were able to push the Union force back through the pass, they had to retreat when their supply train was destroyed and most of their horses and mules killed or driven off. Eventually the Confederates had to withdraw entirely from the territory back into Confederate Arizona and then Texas. Glorieta Pass thus represented the climax of the campaign.

The lower portion of the New Mexico Territory had been largely neglected by both the federal government and the territorial government in Santa Fe. As a result, Confederate sympathy was strong, in hopes of receiving better treatment by the new government. Following secession moves by residents, Confederate forces seized Mesilla and captured the federal troops there, who made a halfhearted attempt to retreat to Santa Fe. In early 1862 the Confederacy established the Confederate Arizona Territory, which included the southern halves of both modern Arizona and New Mexico. The territorial capital was at Mesilla, some 45 miles from El Paso and near today's major city of Las Cruces. The strategic goals were to gain access to the gold and silver mines of California and the Colorado Territory and the seaports in Southern California, and thus evade the Union naval blockade.
