HMS Port d'Espagne was a 14-gun vessel, variously described as a sloop, gun-brig or schooner, built in 1806 in Trinidad, whose citizens presented her to the crown.

Lieutenant James Pattison Stewart was appointed acting commander of Port d'Espagne on the Trinidad station on 15 April 1806.

[b] Three months later, on 6 June, 25 men from Port d'Espagne, under the command of Lieutenant Hall, succeeded in capturing the Spanish privateer schooner Mercedes in the Gulf of Paria.

[5] On 18 August Stewart and Port d'Espagne succeeded in capturing the Spanish privateer schooner Maria after a six-hour chase.

[c] Lastly, Port d'Espagna chased a privateer out of the Gulf of Paria and into the arms of the brig Attentive,[4] which captured the Spaniard on 17 October.

[12] In 1847 the Admiralty authorized the issue of the Naval General Service Medal with the clasp "Martinique" to all remaining surviving claimants of that campaign.
