The affiliation makes the mansion the ninth in the state and the first in Middle Georgia to receive this recognition, according to a news release.
University and Smithsonian officials announced the new affiliation Friday at the Old Governor's Mansion.
"The museum is not only a singular example of Greek Revival architecture, but it is also the place where all Americans can relive a long stretch of our nation's history," Harold Closter, director of Smithsonian Affiliations, said in the release.
The mansion will be part of a select group of museums, cultural, educational and arts organizations that share the Smithsonian's resources with the nation.
"We look forward to building partnerships for exhibitions, loans and the development of programming," Matt Davis, director of the Old Governor's Mansion, said in the release.
There are more than 190 Smithsonian Affiliates in more than 40 states, Puerto Rico and Panama. More than 8,000 Smithsonian artifacts have been displayed at affiliate locations.
