Agua Dulce Airpark (FAA LID: L70), also known as Agua Dulce Airport, is a public-use airport located 2 miles (3.2 km) east of the central business district of Agua Dulce, in Los Angeles County, California, United States.

The plans for an airport at Agua Dulce began in 1958. Aircraft modification engineer Robert W. Lillibridge and Northrop test pilot Errol Williams purchased the vacant acreage for the airport. The costs of subsequent improvements were financed by millionaire businessman Jim Annin. A special permit to begin building was required. On October 27, 1959, Special permit case No. 1404-(5) was granted by the Regional Planning Commission of Los Angeles County. In the 1990s, local residents fought an attempt by Los Angeles County to buy the airpark and convert it to a regional airport. In October 2005, former airport owner Barry Kirschner sold the property to Wayne and Connie Spears, owners of Spears Manufacturing and Spears Motorsports.

Agua Dulce Airpark covers an area of 108 acres (44 ha) which contains one asphalt paved runway (4/22) measuring 4,600 x 50 ft (1,402 x 15 m). For the 12-month period ending May 15, 2006, the airport had 2,880 aircraft operations: 62% transient general aviation and 38% local general aviation.

The airport has been used as a filming location for projects including:
