Captain Archibald Cochrane was a Royal Navy officer of the early nineteenth century, who served in the Napoleonic Wars.

Aboard Speedy, Cochrane participated in the engagement and capture of the Spanish frigate Gamo, which was more than three times the size of the British ship.

Archibald Cochrane was involved in most of his brother's successful operations during the following year, including the capture of the Spanish frigate Gamo on 6 May 1801.

Attacked by the much larger warship, Cochrane took his tiny vessel alongside, and the Spanish sailors could not depress their guns sufficiently to open fire on it.

He later participated in a landing operation at Oropesa del Mar, but was captured when Speedy was seized by a French squadron under Charles Linois on 3 July 1801.
