Wolf Creek Inn State Heritage Site is a state park in the U.S. state of Oregon, administered by the Oregon Parks and Recreation Department. The inn was built along the Applegate Trail in 1883 for Henry Smith, a local entrepreneur. It is the oldest continuously operating inn in the Pacific Northwest, and is the site where author Jack London completed his novel Valley of the Moon. It also housed actors from the early days of Hollywood when they wanted to escape from the studios. Clark Gable, Carol Lombard, and Orson Welles stayed at the inn. The inn was acquired by the Oregon Parks and Recreation Department in 1975. The restaurant and inn are still in operation. The inn was added to the National Register of Historic Places as Wolf Creek Tavern in 1972.
