Vice-Admiral Sir Samuel Cornish, 1st Baronet (c. 1715 – 30 October 1770) was a Royal Navy officer who served in the Seven Years' War.

Cornish was born c. 1715 and joined the Royal Navy in 1728, and having been promoted to lieutenant in 1739, he participated in the battle of Cartagena de Indias in 1741.

When Spain entered the war early in 1762 Cornish was appointed Commander of an East Indies Squadron, who, together with soldiers of the 79th Regiment under William Draper were ordered to attack the Spaniards in the Philippines.

[3] He left his large fortune to his nephew Captain Samuel Pitchford,[1] who at the head of HMS America, had also taken part in the capture of Manila.

A 1768 painting of Cornish, along with his fellow mariner Richard Kempenfelt and his secretary Thomas Parry (a future director of the East India Company) went on permanent display at Queen's House in Greenwich in Autumn 2022.
