Henry Seymour, Lord Beauchamp (c. 1626 – 14 March 1654) was an English nobleman, third son of William Seymour, 2nd Duke of Somerset.
He had two elder brothers, but they both died unmarried in their twenties, so that in 1646, when he was about twenty, Henry became heir to his father and took his courtesy title of Lord Beauchamp. 
On 28 June 1648, he married Mary Capell at Hadham Parva in Hertfordshire; they had one son and one daughter
