Charles Henry Davis (January 16, 1807 – February 18, 1877) was a rear admiral in the United States Navy.
Working for the Coast Survey, Davis researched tides and currents, and located an uncharted shoal that had caused wrecks off the New York coast.
In the Civil War, he commanded the Western Gunboat Flotilla, winning an important engagement in the Battle of Memphis, before capturing enemy supplies on a successful expedition up the Yazoo river.
