The Shelley baronetcy, of Castle Goring in the County of Sussex, was created in the Baronetage of the United Kingdom on 3 March 1806 for Bysshe Shelley (1731–1815). Sir Bysshe was succeeded by his eldest son, Timothy, from his first marriage. Sir Timothy's eldest son and heir apparent was the poet Percy Bysshe Shelley, who predeceased his father, leaving two sons: Charles Bysshe Shelley by his first wife Harriet Westbrook, and Percy Florence Shelley, Shelley's son from his second marriage to the author Mary Shelley. The elder son, Charles, died young, so upon the death of Sir Timothy, the younger son, Percy, became the third Baronet. He died childless and the title passed to his first cousin, Edward Shelley, who then became the fourth Baronet.
