Agua Fria (Spanish for "Cold Water")[3] is an unincorporated community in Mariposa County, California.

[1] It is located 5.25 miles (8.4 km) northeast of Catheys Valley,[3] at an elevation of 2001 feet (610 m).

The camp boasted a hotel, express office, assayers, billiard room, bowling alley, monte and faro banks, about a dozen stores, numerous tents and log cabins by the fall of 1850.

The population started to decline by the mid-19th century, and the city suffered destructive fires and was never rebuilt.

It is accessible via Agua Fria Road to Mount Bullion and the site of Princeton.
