Lowell Ranger Station is a historic Forest Service administrative compound in the Coronado National Forest near Tucson, Arizona. Built in 1934 by the Civilian Conservation Corps from designs by the USDA Forest Service, it reflects the Depression-era expansion of Forest Service work as administration moved beyond basic custodial oversight toward active resource management. Listed on the National Register of Historic Places in 1993, the 2-acre site includes three contributing buildings—an office, a barn/garage, and a house—showing both workplace and government housing functions. Its architectural significance includes Pueblo Revival and related influences, as well as standardized Regional Office planning typical of 1930s Forest Service complexes in Arizona.
