The Oregon Sentinel was the first newspaper in southern Oregon, United States. It was published in Jacksonville, Oregon from 1855 to 1888. It was founded by William G. T'Vault. It was initially named the Table Rock Sentinel, changing its title in 1858. It was a decidedly pro-slavery newspaper. The Jacksonville Sentinel, a distinct newspaper, was founded in 1902 and lasted until 1906. It was the only Republican paper in southern Oregon at the time. It was edited by Joseph P. Gaston. In the 1980s, the Southern Oregon Historical Society revived the title once again for its own newsletter.
