Fairfield Plantation, Plantation house near McClellanville, Charleston County, South Carolina, US

Fairfield Plantation, also known as the Lynch House, is a Georgian-style clapboard house on a raised basement about 5 mi east of McClellanville, just off US Highway 17 near the Santee River. Its pedimented south and north porches are each carried by six Doric columns, two of them engaged; the landside south porch rests on brick columns and the riverside north porch on brick arches. The house has a hip roof and two cross-shaped interior chimneys.

The house was built around 1730 by the Lynch family and later came under the ownership of the Pinckney family, who held it for over 200 years. This extended ownership connected it to one of South Carolina's most influential families in the region's development.

The house is also known as the Lynch House, after the family believed to have built it around 1730. In 1758 it passed to Jacob Motte, son of the provincial treasurer, and his wife Rebecca Brewton Motte; their daughters Elizabeth and Frances both married Thomas Pinckney in succession, and the property stayed with the Pinckney family for over 200 years.

Fairfield Plantation stands about 5 mi (8 km) east of McClellanville, just off US Highway 17 and near the Santee River; it is adjacent to Wedge Plantation and just north of Harrietta Plantation. The house is on private land, so it is seen from the road rather than toured inside.

The south porch rests on brick columns, while the riverside north porch uses brick arch supports; the six-column porches were probably added in the late 18th century. The second floor was squared out with two extra river-facing rooms after Jacob Motte acquired the house in 1758.
