Sir John Hadley D'Oyly, 6th Baronet (January 1754, Ipswich 5 January 1818, Calcutta, Bengal, British India) was a politician in Great Britain. He primarily inherited debt when his father died when he was ten, but through family connections had a successful career with the East India Company. Returning to Ipswich a wealthy man, he settled his fathers debts and aligned himself with the Ipswich Yellow Party. He served as the MP for the town for several years in the 1790s. He returned to India in 1803 where he lived until his death in 1818.
