Historic Oakleigh is a museum complex located in the Oakleigh Garden Historic District near downtown Mobile, Mobile County. The site, which includes the Oakleigh mansion, a cottage, a Union barracks, and an archive, is owned by the Historic Mobile Preservation Society (HMPS) and interprets pre-1850 society. The main house also serves as exhibit space for artworks. The home was documented by the Historical American Buildings Survey in 1935 and placed on the National Register of Historic Places in 1971.

James W. Roper, a brick mason, dry-goods merchant, and cotton factor from James City County, Virginia, began construction of the home in 1833 on 35 acres that were outside the city limits at the time. He designed the staircase, which is a quarter-turn, cantilevered staircase that rises to the front door. Enslaved people constructed the home, making its bricks from clay dug on the property. No slave quarters remain, however. During its construction, Roper's wife, Sarah Ann Davenport, and their child died. In 1838, he married Eliza Ann Simison, the same year construction on the house finished. The couple would have four children.
Roper had borrowed $20,000 to build Oakleigh, but the Panic of 1837 caused financial distress, and he was unable to pay off his loans. The house was repossessed, but Roper's brother-in-law Boyd Simison bought Oakleigh and half the acreage of the estate and Roper's 18 enslaved persons. He allowed the Roper family to remain in the home until 1850. Simison also paid for a remodel of the home after an 1840 fire damaged it.
In 1852, Alfred Irwin, a treasurer of the Mobile & Ohio Railroad, purchased the home and lived there with his wife, Margaret Kilshaw. During the Civil War, the Irwins used their British citizenship to protect the estate, claiming the property was neutral and hanging a Union Jack from the balcony. Their sons, however, both served in the Confederate States Army and gained local prominence for their involvement. The house passed through several owners until it was bought in 1916 by Herbert Cole, a doctor, and his wife, who owned the property until 1955, when it was purchased by the city of Mobile.
