Chama was originally part of the Tierra Amarilla Land Grant. In 1880 the Denver & Rio Grande Railroad began construction of its San Juan Extension from Antonito, Colorado westward toward a mining district in the northern San Juan Basin of Colorado. The railroad needed an engine terminal for helper locomotives, near to the western foot of the steep gradient toward Cumbres Pass. It chose a site on the western bank of the Rio Chama where the railroad crossed it, for the terminal and its supporting townsite, naming the village for the river crossing. Train service began on February 1, 1881 and a post office was established that year.
