Sonoma Valley Airport (FAA LID: 0Q3) is a public-use airstrip founded in 1946 by Wally Reichelt in Sonoma, California, United States.

Open to public use for light aircraft, Sonoma Valley Airport does not allow ultralight and rotorcraft operations, except for MEDEVAC or law enforcement helicopters.

Among other fixed-wing aircraft, vintage planes can be seen on Sonoma Valley's apron, such as a fully restored, flying Curtiss P-40, a North American SNJ-4, three Boeing-Stearman PT-17 biplanes, a Globe Swift, a Cessna 195, a Douglas DC-3, a Dornier Do 27 or a Seabee amphibious.

Vintage Aircraft offers flights in restored WWII open cockpit Stearmans and AT6 Texan.

The airport was threatened by the development of a fly fishing business next door in 2012.
