Kneeland Airport (IATA: NLN, FAA LID: O19) is a public airport operated by Humboldt County 10 miles (16 km) southeast of Eureka, California. Located on a mountain ridge at over 2,700 feet (820 m) above sea level, this airfield is used by general aviation aircraft, which sometimes seek an alternate airport when nearby low-lying airports are under fog. The airport has a California Dept. of Forestry (CDF) Helitack Station.
Kneeland Airport covers 14 acres (57,000 m2). Its one runway, 15/33, is 2,252 by 50 feet (686 by 15 m) and is asphalt paved.
The airport bisects the only known population of the Kneeland Prairie pennycress (Thlaspi californicum), a federally listed endangered plant species.
