Rock Bluff is a ghost town in Cass County located approximately three miles east of Murray in the U.S. state of Nebraska.

Once the home of an influential college called the Naomi Institute, Rock Bluff was instrumental in the 1866 vote that gave Nebraska statehood.

Settled in 1854 by a German named Benedict Spires, Rock Bluffs became a leading point for equipping freighting outfits to cross the plains during the 1850s.

By 1877 it had almost 200 residents, as well as a Methodist Church,[2] a post office, a mayor, the county fair, a common lodge hall for Masons and Odd Fellows, and a variety of businesses including three stores, two blacksmith shops, two saloons and a billiard hall.
