Pine Castle is a census-designated place and unincorporated area in Orange County, Florida, United States.

Initially settled in 1870, the town's development has been shaped by that of Orlando, approximately 5 miles (8 km) to the north.

In 1925, boat manufacturer Correct Craft founded its original factory in Pine Castle, before constructing a larger facility in 2006.

[citation needed] In the mid-1940s, Bell Aircraft Corporation tested its X-1 supersonic rocket plane at Pinecastle Army Airfield, because of the area's then-remote location and 10,000-foot (3,000 m) runway.

[11] The airfield, located 2 miles (3 km) southeast of Pine Castle, has since become Orlando International Airport.

The Pine Castle Christian Academy won state championships in three high school sports.
