Alegres Mountain is a notable summit in the Mangas Mountains on the Colorado Plateau in western New Mexico, about 10 miles southwest of Pie Town. It is the 180th highest peak in the state and ranks 30th in New Mexico for topographic prominence. Reached by Dipping Vat Road, also called Pipeline Springs Road, the mountain stands out for its position within the Mangas Mountains and for its relatively high prominence in this remote part of Catron County.
