Thomas North Graves, 2nd Baron Graves (28 May 1775 – 7 February 1830) was a British peer and Member of Parliament.
Graves was the son of Admiral Thomas Graves, 1st Baron Graves. He succeeded his father as second Baron Graves in 1802, but as this was an Irish peerage it did not entitle him to an automatic seat in the House of Lords. He was instead elected to the House of Commons for Okehampton in 1812, a seat he held until 1818, and then represented Windsor from 1819 to 1820 and Milborne Port from 1820 to 1827, when he retired from the Commons to become one of His Majesty's Commissioners of Revenue of Excise. He was also a Lord of the Bedchamber and Comptroller of the Household to His Royal Highness Ernest Augustus, 1st Duke of Cumberland and Teviotdale.
Lord Graves married Lady Mary Paget, daughter of Henry Bayly Paget, 1st Earl of Uxbridge, in 1803. They had twelve children, five sons and seven daughters:
