Mound Cemetery in Marietta, Ohio, is a historic cemetery developed around the base of a prehistoric Adena burial mound known as the Great Mound or Conus. The city founders preserved the Great Mound from destruction by establishing the city cemetery around it in 1801.

The city of Marietta was developed in 1788 by pioneers from Massachusetts, soon after the American Revolutionary War and organization of the Northwest Territory. Many of the founders were officers of the Revolutionary War who had received federal land grants for military services. Among high-ranking officers buried at the cemetery are generals Rufus Putnam and Benjamin Tupper, who were founders of the Ohio Company of Associates, as well as Commodore Abraham Whipple and Colonel William Stacy. The cemetery has the highest number of burials of American Revolutionary War officers in the country.
