The SS City of Chester was a steamship built in 1875 that sank after a collision in a dense fog with SS Oceanic at the Golden Gate in San Francisco Bay on August 22, 1888. She was owned by the Oregon Railroad Co. and leased by the Pacific Coast Steamship Company. The wreck was relocated in May 2013 by NOAA Office of Coast Survey Navigational Response Team 6 with multi-beam sonar.
