Riverside is an unincorporated community in Grant County, New Mexico, United States.

[1][2] It lies on the left (east) bank of the Gila River and on both sides of U.S. Route 180 in southwestern New Mexico, 2.6 miles (4.2 km) by road south of Cliff.

Riverside and the surrounding area in the Gila River Valley were settled by Anglos in 1884, as fear of Apache raiders decreased.

[5] In 1900, Thomas Jefferson Clark built a two-story hotel in Riverside as a type of caravanserai for travellers on the stage route between Mogollon and Silver City.

[6] The annual Audubon Gila River bird count takes place in Riverside.
