Ravenna is a historic two-and-a-half-story mansion in Natchez, Mississippi, U.S.. It was built in 1835-1836 for William Harris, a merchant commissioner, planter and Natchez alderman. It was designed in the Greek Revival architectural style, based on plans by Asher Benjamin. By the 1850s, it was purchased by the Melcalfe family, whose descendants owned the house until they sold it to Dr. Mallan Morgan in the 1980s. It has been listed on the National Register of Historic Places since November 4, 1982.
