Cannonball House, History museum in Macon, Georgia, United States.

The Cannonball House is a Greek Revival house built in 1853 at 856 Mulberry Street for Judge Asa Holt. Its front facade has a two-story columned portico; the left middle column still shows where a Union cannonball struck on July 30, 1864. Behind the house stands a hand-molded two-story brick kitchen, with servants' quarters on the upper level.

The house was built in 1853 as a townhouse for a wealthy judge. During the conflicts of 1864, a cannonball struck it, giving the building its lasting name.

The house holds collections from two national collegiate women's societies: the Adelphean Collection from Alpha Delta Pi and the Philomathean Collection from Phi Mu. These objects show how important these organizations were for women's education history.

The house is run as a historic house museum by The Friends of the Cannonball House. Visitors can tour the rooms, browse the Civil War collection, join educational programs, walk the garden and visit the gift shop. The two-story brick kitchen and servants' quarters at the rear are part of the visit.

The cannonball entered through the left middle column of the front facade, crossed a parlor and came to rest in the interior hallway; no one was hurt. The house was the only home in Macon damaged in the July 30, 1864 bombardment, fired from across the Ocmulgee River during the Battle of Dunlap Hill.
