Colonel Thomas Lygon III (also spelled Ligon, Liggon and Liggin; 11 January 1623 – 16 March 1675) was a Colonial Virginian statesman, militia officer, and landowner. Born into a genteel family in England, Lygon emigrated to the Virginia Colony in the early 1640s. He served in the House of Burgesses, representing Henrico County, and was a justice of the peace for Charles City County. Lygon owned large parcels of land along the Appomattox River, and worked as a surveyor until his death in 1675. He was the patriarch of the American branch of the Lygon family.
