Cave Junction is a city in Josephine County, Oregon, United States. As of the 2020 census, the city population was 2,071. Its motto is the "Gateway to the Oregon Caves", and the city got its name by virtue of its location at the junction of Redwood Highway and Caves Highway. Cave Junction is located in the Illinois Valley, where, starting in the 1850s, the non-native economy depended on gold mining. After World War II, timber became the main source of income for residents. As timber income has since declined, Cave Junction is attempting to compensate with tourism and as a haven for retirees. Tourists visit the Oregon Caves National Monument and Preserve, which includes the Oregon Caves Chateau, as well as the Out 'N' About treehouse resort and the Great Cats World Park zoo.
