Newark Liberty International Airport (IATA: EWR, ICAO: KEWR, FAA LID: EWR), first named Newark Airport and later Newark International Airport, je mezinárodní letiště na území měst Newark a Elizabeth v New Jersey. Nachází se 24 km jihozápadně od Manhattanu.
Letiště provozuje Port Authority of New York and New Jersey, which also manages the two other major airports in the New York/New Jersey metropolitan area, John F. Kennedy International Airport (JFK) and LaGuardia Airport (LGA), in addition to three smaller airports, Stewart International Airport, Teterboro Airport and the Downtown Manhattan Heliport. Newark is the tenth busiest airport in the United States and the nation's fifth busiest international air gateway; JFK ranks first.
Newark Liberty je druhou největší základnou Continental Airlines, který je největším nájemcem letiště (operating all of Terminal C and part of Terminal A). Primarily due to this large hub operation, Continental Airlines is by far the leading carrier in the New York market. FedEx Express operates one of its major cargo hubs at Newark.
V roce 2007, Newark Airport odbavilo přes 37 milionů pasažérů, což je o 10 milionů méně, než JFK, ale o 10 milionů více, než LaGuardia. In total over 111 million passengers used New York airports in 2007, making New York the busiest airport system in the United States in terms of passenger numbers and second in the world behind London.
