The First Battle of Mesilla was fought on July 25, 1861, at Mesilla in New Mexico Territory, in present-day Doña Ana County, New Mexico. It was an engagement between Confederate and Union forces during the American Civil War. The battle resulted in a Confederate victory and led directly to the establishing of a Confederate Arizona Territory, consisting of the southern portion of the New Mexico Territory. The victory paved the way for the Confederate New Mexico Campaign the following year.
