Gov. William Aiken House, Antebellum residence in Charleston, South Carolina.

The Gov. William Aiken House is a two-story residence in Charleston, South Carolina, built in the Federal and Adam architectural style. It has a large porch on its southern side, multiple courtyards, two ballrooms, and a series of rooms arranged for formal gatherings.

John Robinson built the house in 1820 after buying lots in Mazyck-Wraggborough in 1817; it was first laid out as a Charleston double house entered from Judith Street on the south. William Aiken Sr., owner of the South Carolina Canal and Railroad Company, then his son Governor William Aiken Jr. lived here, and the family kept it for over 142 years. Frances Dill Rhett donated it to the Charleston Museum in 1975; Historic Charleston Foundation bought it in 1995 and runs it as a museum.

The house takes its name from Governor William Aiken, once among the wealthiest men in the American South. The two ballrooms and formal reception spaces give a clear picture of how Charleston's elite gathered and entertained guests in the 1800s.

The house stands at 48 Elizabeth Street in Wraggborough, at the corner of Judith Street, where the original entrance faced south. Historic Charleston Foundation runs it as a museum; its self-guided audio tour, launched in 2018, lasts about 45 minutes and includes exhibit descriptions and photographs. The slave dwellings and artifact exhibits lie in separate outbuildings, so allow time to walk the whole complex.

In 2016 archaeologists began surveying the slave dwellings behind the house; by 2018 they had recovered more than 10,000 artifacts, from coins and tools to bottle and pottery fragments, most now displayed in an exhibit on the site. A separate 2017 survey looked for traces of siege lines British soldiers reportedly dug in spring 1780.
