Louisiana Governor's Mansion, Official residence near Capitol Lake in Baton Rouge, United States.

The Louisiana Governor's Mansion is a Greek Revival residence overlooking Capitol Lake in Baton Rouge, built of hand-molded brick painted white. White Doric columns line three sides, and the roof is cleft-face Vermont gray-green slate. The interior has twelve bedrooms, eighteen baths, two kitchens, a rotunda with a spiral stairway, and a foyer mural updated after Hurricane Katrina.

Built in 1963 while Jimmie Davis was governor, the mansion was designed by the Shreveport firm Annan and Gilmer at a final construction cost of $893,843. Its exterior took Oak Alley Plantation in Vacherie as its model, though the second-floor veranda was left off as too informal for a governor's residence. The foyer mural, painted in 2000 under Mike Foster, was later updated with references to Hurricane Katrina and Governor Kathleen Blanco.

The foyer mural was painted in 2000 under Governor Mike Foster and depicts scenes of Louisiana history alongside symbolic references to past governors. It was later updated with references to Hurricane Katrina and Governor Kathleen Blanco.

The mansion stands at 1001 Capitol Access Road (LA-3045), Baton Rouge 70802, on an 8-acre parcel overlooking Capitol Lake near the State Capitol. Tours of the interior are given by appointment only, so arrange a visit in advance rather than arriving unannounced.

The exterior was modelled on Oak Alley Plantation in Vacherie, Louisiana, but its second-storey veranda was left off as too informal for a governor's house. The lamp posts in the parking lot east of the building once burned gas in Plymouth, England.
