North Palm Beach County Airport (FAA LID: F45), also known as North County Airport, is an uncontrolled (non-towered) general aviation airport located 12 nautical miles (22 kilometres) northwest of West Palm Beach off the Bee Line Highway in Palm Beach Gardens, Florida. The airport is owned by Palm Beach County and operated by the Palm Beach County Airports Department. Opened in 1994, it is the county's newest airport. It is located next to the site of the "fake" town of Apix, Florida.

The field is in proximity to, and shares services with, William P. Gwinn Airport (FAA LID: 06FA) (more commonly referred to as Gwinn Airfield) which is owned by United Technologies Corporation (UTC). It was previously operated by its Pratt & Whitney jet engine business unit and is currently operated by its Sikorsky Aircraft business unit. Due to its proximity to the Sikorsky test grounds, North County is often used to test ILS approaches on experimental or prototype helicopters such as the RAH-66 Comanche, SH-60 Seahawk and the S-92.

DayJet previously provided an on-demand jet air taxi service from this airport to Jacksonville, Lakeland, Tallahassee, Pensacola, Gainesville, Boca Raton, Opa-Locka/Miami Dade County, Naples, Sarasota/Bradenton, Savannah, Macon, and Montgomery until its liquidation in bankruptcy in 2008.
