Sir John Shelley, 5th Baronet (1730 – 11 September 1783), of Michelgrove in Sussex, was a British politician who sat in the House of Commons from 1751 to 1780.
He entered Parliament at a by-election in 1751, probably at the first opportunity once he was legally old enough to do so, as Member of Parliament for East Retford, a pocket borough owned by his uncle Newcastle; the vacancy arose from the appointment of the sitting MP as a Commissioner of the Excise, quite possibly with the specific intention of freeing the seat for Shelley.
In 1757 he acquired another lucrative post, Clerk of the Pipe, and in 1766 he became Treasurer of His Majesty's Household and was appointed to the Privy Council.
Shelley succeeded to the baronetcy on his father's death on 5 September 1771, taking possession of Michelgrove, Sussex.
