Baron Hamilton of Hameldon, of Hambledon in the County of Leicester, is a title in the Peerage of Great Britain, held by the Duke of Hamilton from 1790 to 1799 and by the Duke of Argyll since 1799.

She died in 1790, and her Barony passed to her only surviving son from her first marriage, the 8th Duke of Hamilton.

On his death without male issue, the barony passed to his half-brother the Marquess of Lorne, the Duchess's eldest surviving son by her second marriage.

Lord Lorne succeeded his father as 6th Duke of Argyll in 1806, and the Barony of Hamilton has since remained united with that title.
