Cornville is a census-designated place (CDP) in Yavapai County, Arizona, United States. The population was 3,335 at the 2000 census. The Cornville CDP includes the communities of Cornville and Page Springs.
Cornville and Page Springs are rapidly growing suburban areas that serve as bedroom communities for nearby Sedona and Cottonwood. Both communities are located along Oak Creek, a tributary of the Verde River. Lower Oak Creek has been designated an Important Bird Area by the National Audubon Society. Page Springs hosts a large fish hatchery operated by the Arizona Game and Fish Department. Adjacent to the hatchery are creekside hiking trails and bird-watching areas.
Cornville's best known resident is U.S. Senator and 2008 Republican Presidential candidate John McCain. McCain's home in the community, referred to in the media as his "Sedona Cabin," is where he and his running-mate, Alaska governor Sarah Palin, prepared for their debates.
Cornville has a Greater Cornville Community Association, which meets monthly.
