Osan (Korean: 오산; Korean pronunciation: [o.san]) is a city in Gyeonggi Province, South Korea, approximately 35 km (22 mi) south of Seoul. The population of the city is around 200,000. The local economy is supported by a mix of agricultural and industrial enterprises.

It is famous for one of the largest markets in South Korea, Osan Market, which has been in continuous operation since 1792.^{[citation needed]} The city was the scene of the first battle between the US and North Korea during the Korean War in 1950; there is a statue and museum dedicated to UN forces on the outskirts of the city.

The United States Air Force base named after the city, Osan Air Base, is not actually located in the city, but is instead 8 km (5.0 mi) south, in the Songtan district (formerly a separate city) of Pyeongtaek.

Osan Station is a large subway station located in the heart of Osan. It is part of the Seoul Subway Line 1 and the KTX. There is a bus terminal next to the subway station and many buses stop in front of the subway station.
