Admiral Henry Osborn (baptized 27 August 1694 – 4 February 1771) was a British naval officer who served as Commodore-Governor of Newfoundland.

[1] In late 1757 Osborn besieged the neutral port of Cartagena in Spain[1] where a French squadron designed to go to the relief of Louisbourg had taken shelter.

While there he attacked a small French squadron under Michel-Ange Duquesne de Menneville which was coming to the aid of the trapped force.

The battle helped to restore the Royal Navy's reputation following the failed attempt to relieve Minorca two years earlier which had led to Admiral Byng's execution.

[4] On 1 January 1763, he received the honorific post of Vice-Admiral of Great Britain.
