Sir John Saunders Sebright, 7th Baronet, DL (23 May 1767 – 15 April 1846), of Besford, Worcestershire, and Beechwood Park, Hertfordshire, was an English politician and agricultural innovator.
Born on 23 May 1767 in Sackville Street, St. James's, he was the eldest son of Sir John Sebright, 6th Baronet, by Sarah, daughter of Edward Knight, of Wolverley, Worcestershire.
On 5 April 1821 he seconded Lord Cranborne's motion for an inquiry into the game laws, and supported subsequent bills for their amendment.
He built and endowed a school at Cheverell's Green, and a row of almshouses for sixteen paupers in the parish of Flamstead, Hertfordshire, where some of the family property lay.
Charles Darwin commented on Sebright's practical skill as a breeder in The Variation of Animals and Plants Under Domestication.
