The Oregon and California Railroad Revested Lands (commonly known as O&C Lands), are approximately 2,600,000 acres (1,100,000 ha) of land located in eighteen counties of western Oregon. Originally granted to the Oregon & California Railroad to build a railroad between Portland, Oregon and San Francisco, California, the land was reconveyed to the United States government by act of Congress in 1916 and is currently managed by the United States Bureau of Land Management.
