Monterey Bay Academy Airport (FAA LID: CA66) is a small daytime only airfield located near the city of Watsonville in Santa Cruz County, California, United States.

This private-use airport is owned by the Seventh-day Adventist Church and is located on the campus of Monterey Bay Academy, previously the military installation Camp McQuaide.

Improvements and management of the airstrip were previously directed by Ocean Shore Aviation.

In the 1940s, a small aircraft landing strip was built at Camp McQuaide so airplanes could drop targets into the ocean.

After the end of the war, in 1948, it was converted to the private boarding school Monterey Bay Academy.
