The Cookes Range (Cooke's Range, Cooks Range or Cook's Range) is a small, 17-mi (27 km) long mountain range in northern Luna County, New Mexico, which extends slightly north into southeastern Grant County. The range is a southern continuation of the Mimbres Mountains, itself the southeast portion of the extensive north–south running Black Range. The Cookes Range is surrounded by lower elevation areas of the northwest Chihuahuan Desert.
