George Seton, Lord Seton, Master of Winton (15 May 1613 – 4 June 1648) was a Scottish landowner. He was the eldest surviving son of George Seton, 3rd Earl of Winton and Anna Hay. He continued the family's long-standing Roman Catholic traditions. Through his father's influence, in 1639 he married Lady Henrietta Gordon, daughter of the Marquess of Huntly, with whom he made a great match and by whom he had four sons, of whom George succeeded his grandfather as fourth Earl of Winton, and the others died young or without issue.
