Whitney Plantation Historic District, African American museum in St. John the Baptist Parish, Louisiana, United States.

Whitney Plantation Historic District is a museum near Wallace, Louisiana, on the River Road along the Mississippi River, where 200 acres (81 ha) of the original 1,500-acre (610 ha) property hold the historic complex. Its centerpiece is the French Creole raised-style main house, built around 1790, a two-story building with a wide covered gallery, square white columns, a slatted balustrade on both levels, and two dormers on a low-pitched brown-shingled roof. Outbuildings include a dovecote, a detached kitchen, an overseer's house, a mule barn, two slave cabins, and the only surviving French Creole barn in North America, also from around 1790.

Ambroise Heidel, a German immigrant, founded the property in 1752 as Habitation Haydel and grew indigo. His son Jean-Jacques converted it to sugarcane around 1800, and under Marie Azélie Haydel it became one of Louisiana's most profitable sugar plantations. Sold in 1866 to Bradish Johnson, it was renamed Whitney after his daughter. Farming ceased in 1975, and the site opened as a slavery museum in 2014.

The museum tells the story from the perspective of the enslaved rather than the owners. Its grounds hold memorial sites for the more than 100,000 men, women and children enslaved in Louisiana, and life-size sculptures of children commissioned by founder John Cummings represent people born into slavery before the Civil War.

Visitors can explore the grounds with a self-guided tour or a 90-minute audio guide, available from 9:30 AM to 4:30 PM. The museum is closed on Tuesdays, and visitors should plan time for walking the outdoor areas.

The Federal Writers Project interviews from the 1930s preserve direct testimony from the last people who experienced slavery at this site. These recordings offer a rare chance to hear the voices of survivors.
