Amador County Airport (ICAO: KJAQ, FAA LID: JAQ, formerly O70), also known as Westover Field, is a county-owned public-use airport in Amador County, California, United States. It is located two nautical miles (3.7 km) northwest of the central business district of Jackson, California. The airport is mostly used for general aviation.

Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this facility is assigned JAQ by the FAA but has no designation from the IATA (which assigned JAQ to Jacquinot Bay Airport in Papua New Guinea).
