Toyama Airport (富山空港, Toyama Kūkō) (IATA: TOY, ICAO: RJNT) is an airport located in the city of Toyama, Toyama Prefecture, Japan. It services are primarily domestic flights and international flights to China and Taiwan: however, seasonal international charter flights also service Toyama from April to June.

Located approximately 7 km (4.3 mi) south of central Toyama, the airport is part of the Tateyama Kurobe Alpine Route and is the closest international airport to UNESCO World Heritage Site of Gokayama. As the airport has convenient access to downtown Toyama and various highways, the airport also serves a wide area of the Jōetsu region of Niigata Prefecture and Hida region of Gifu Prefecture.

The airport opened on August 20, 1963, with regularly scheduled flights by All Nippon Airways to Tokyo Haneda Airport using a Fokker F-27. This was replaced by a NAMC YS-11 in 1970. In 1984, the runway was lengthened from 1200 to 2000 meters to accommodate jet operations and a new terminal building was completed. An international terminal was completed in March 1993, Asiana and Aeroflot becoming the first international airlines to schedule service to the airport from Seoul and Vladivostok respectively. In late 1990s, Aeroflot terminated the link to Vladivostok, while Asiana retained it.

It is the only airport built on a riverbed in Japan, and the runways and aprons are located on the riverbed on the right bank of the Jinzū River.
