Nathanael Greene Monument, Revolutionary War memorial in Johnson Square, Savannah, United States.

The Nathanael Greene Monument is a 50-foot granite shaft in Johnson Square, designed by William Strickland and completed in 1830. Two bronze plaques were added to opposite sides in 1853, one bearing a bas-relief of Greene. Greene's body was reinterred beneath it in 1902.

The monument marks the burial site of Major General Nathanael Greene, one of George Washington's most effective commanders during the Revolutionary War. The cornerstone was placed by Marquis de Lafayette in 1825, linking two major figures of the American Revolution.

The monument became Savannah's Greene monument in 1853, once a separate Pulaski memorial rose in Monterey Square. Two bronze plaques were unveiled on 6 May 1885, one with a bas-relief of Greene; former Confederate president Jefferson Davis, whose father served under Greene, spoke at the ceremony. In October 2018 googly eyes were stuck to the bas-relief, drawing national coverage.

The location sits in the center of Johnson Square and is easily reached from East Congress Street and East Saint Julian Street in downtown Savannah. The square can be viewed from multiple angles and is straightforward to explore on foot.

In October 2018, googly eyes were stuck onto the bronze bas-relief of Greene, and the vandalism was reported by CNN, CBS News and USA Today. The police investigated it as criminal trespass and possible criminal damage, depending on the repair cost.
