Corotoman was a 17th and 18th century plantation on the Rappahannock River in Lancaster County, Virginia, United States. Corotoman was the residence of Robert Carter I (1662/63 – 4 August 1732), a colonial Governor of Virginia and one of the wealthiest men in the British colonies in North America. Corotoman was located on a point overlooking the Rappahannock River, and flanked by Carter's Creek and Corrotoman River to its east and west respectively.
John Carter I, the patriarch of the Carter family of Virginia, purchased and settled Corotoman between 1652 and 1653. Carter developed and improved the lands into a plantation and constructed the first structures on the property before his death in 1669. Carter's mansion, known as the "Old House", was built in the traditional 17th century hall-parlor plan with a porch chamber.
Corotoman was then inherited by Carter's son Robert Carter I (whose wealth and autocratic business methods led to his becoming known by the nickname "King") in 1690. Under Robert Carter I's ownership, Corotoman became the center of what developed into a 300,000-acre (1,200 km2) estate of 48 plantations and farms including places such as Indian Town and Hills Quarters.
