Mangas Mountain Lookout Complex is a historic fire lookout on Mangas Mountain near Mangas, New Mexico. Built in 1934, it includes a fire lookout tower and a cabin or cottage. The complex gained recognition on the National Register of Historic Places in 1988, where it was identified as significant for two contributing elements: one building and one structure. Its importance lies in preserving a historic lookout site made up of the tower and its associated living or support quarters.
