Mohawk is an unincorporated community in Yuma County, Arizona, United States. It is part of the Yuma Metropolitan Statistical Area.
Mohawk is located on the south border of the Gila River valley on Interstate 8; it is 13 miles east of Tacna, also on Interstate 8. East of Mohawk is Dateland and Aztec. Just northeast located in the Gila River valley is Hyder which lies in the Hyder Valley at the southern end of the Palomas Plain, draining southeastwards from the eastern perimeter of the Kofa National Wildlife Refuge, and the eastern regions of the US Army Yuma Proving Ground.
Mohawk is located at the northern end of the Mohawk Mountains–Bryan Mountains block faulted ranges, which are part of an eleven mountain range–valley region in southern Yuma County. The Mohawk Valley drains northwestwards towards Mohawk on the west of the ranges; the San Cristobal Valley drains mostly north on the east side of the ranges. The drainages do not make it to the Gila River because the region is an extensive region of valleys–bajada plains. The area is part of the central, and hot and arid southwestern region of the Sonoran Desert. It is also just north of the Gran Desierto de Altar and Pinacate Reserve of northern Sonora, Mexico.
