Green River Plantation, Historic plantation house in Columbus, North Carolina, United States.

Green River Plantation is a large mansion in Columbus, North Carolina, consisting of two connected sections that display Federal and Greek Revival architectural features. The building was constructed in two phases and combines different architectural approaches from the early 1800s.

Joseph McDowell Carson, son of Colonel John Carson who built the Carson House at Marion, built the oldest section of the house between 1804 and 1807. A second brick Greek Revival dwelling was added beside it in the mid-19th century and served as the residence of his younger brother Samuel Price Carson, a state senator and U.S. Federal Representative. The two sections were joined in the late 19th century by a two-story linking section with a grand staircase. The property was listed on the National Register of Historic Places in 1974.

The house displays architectural elements from two different building periods, which you can still observe today and show how construction styles changed in the region over time.

The property is open for various events including weddings and concerts, and guided tours of the house are available. It is helpful to check ahead about availability and specific conditions for visiting.

The two halves of the house were built for two brothers: Joseph McDowell Carson raised the 1804–1807 Federal section, while the mid-19th-century brick Greek Revival block was the home of Samuel Price Carson, a state senator and U.S. representative. A late 19th-century two-story link and grand staircase joined them into one structure of more than 42 rooms and over 10,000 square feet.
