Church Rock (Navajo: Kinłitsosinil) is a census-designated place (CDP) in McKinley County, New Mexico, United States.

[5] It is bordered to the west by Gallup, the county seat, to the southwest by Sundance, and to the east by Iyanbito.

U.S. Route 66 runs along the southern edge of the community, leading west 7 miles (11 km) into Gallup and east the same distance to Exit 36 on Interstate 40.

According to the U.S. Census Bureau, the Church Rock CDP has a total area of 18.3 square miles (47 km2), all of it recorded as land.

On July 16, 1979, the dam at a United Nuclear Corporation (based in Virginia) Church Rock uranium mill was breached and spilled 1,100 tons of milled uranium ore and 94 million US gallons (360,000 m3) of heavy metal effluent into the Puerco River.

This was the largest release of radioactive waste in U.S. history, but until recently, no epidemiological studies were undertaken on the effects on the population.

[7] In 2003 the Church Rock Uranium Monitoring Project was initiated by the Churchrock Chapter of the Navajo Nation to assess environmental impacts of abandoned uranium mines and build capacity to conduct community-based research with policy implications.
