The Mississippi Governor's Mansion is the official residence of the governor of Mississippi, who is currently Tate Reeves. It is located in downtown Jackson, Mississippi, south of the Mississippi State Capitol, at the south end of Smith Park. Completed in 1841 to a design by state architect William Nichols, it is the second-oldest governor's residence in active use in the nation, and a prominent example of Greek Revival architecture. It was designated a National Historic Landmark in 1975, and was declared a Mississippi Landmark in 1985.

The governor of Mississippi is the head of government of Mississippi and the commander-in-chief of the state's military forces. The governor has a duty to enforce state laws, and the power to either approve or veto bills passed by the Mississippi Legislature, to convene the legislature at any time, and, except in cases of treason or impeachment, to grant pardons and reprieves.
