Matthew Duane (1707–1785) was an English Roman Catholic conveyancer and art patron.
Of obscure family origins, by the 1730s Duane had established himself as a 'chamber counsel' and conveyancer in Newcastle and London.
Amongst his pupils were Lord Eldon and Charles Butler.
Duane was a Fellow of the Royal Society and of the Society of Antiquaries, and a trustee of the British Museum, and had a reputation as a leading collector of coins and medals.
