Live Oak, Colonial plantation in Weyanoke, United States.

Live Oak is a plantation house built in 1808 in Weyanoke, West Feliciana Parish, Louisiana, on a property of more than 100 acres. Cyrus Ratliff built the Anglo-American house at the center of the land; the historic area of 155 acres (63 ha) includes Little Bayou Sara and the abandoned old Tunica Road.

The house was built in 1808 while the area was still under Spanish rule, just before the United States took control of the Republic of West Florida in 1810. Its construction marks a moment when the region was passing from one government to another.

The house has served as a rent house, post office, schoolhouse and apothecary store over the plantation's more than 200-year history. The property is currently owned by architect Victor F. Trahan. The 155-acre historic area takes in Little Bayou Sara and the abandoned old Tunica Road.

The property sits between two small towns in West Feliciana Parish and is best explored on foot, as the grounds around the house cover a good amount of open land. Giving yourself extra time is a good idea, since walking the full site takes longer than expected.

The 155-acre historic area listed in 1977 takes in Little Bayou Sara and the abandoned old Tunica Road, not just the house. The property passed through many uses over two centuries, among them a rent house, a post office, a schoolhouse and an apothecary store.
