HMS Ballahoo (also Balahou, Ballahou or Ballahon) was the first of the Royal Navy's Ballahoo-class schooners, vessels of four 12-pounder carronades and a crew of 20.

On 27 February 1807 the sloop Port d'Espagne and the schooner Express captured the brig Altrevido, Nichola Valpardo, master.

[5] On 4 August 1807, Ballahoo was in company with the schooner Laura, of 10 guns, when they encountered the French letter of marque Rhone some five or six leagues N by E of Tobago.

[6] Rhone, under the command of Francis Goureu, was of 90 tons (bm), mounted six long 6-pounder guns, and was 10 days out from Martinique, having captured nothing.

[2] On 3 July, whilst Ballahoo was cruising with the ship-sloop Wanderer, under Commander Edward Crofton, and the schooner Subtle, Lieutenant George A. Spearing, between the islands of Anguilla and Saint Martin, the small squadron attempted an attack on St. Martin with a view to reducing the number of havens available to French privateers, but unfortunately the opposition proved stronger than intelligence had suggested.

A landing party of 38 seamen and marines from all three vessels, under Lieutenant Spearing, succeeded in capturing a lower battery with few losses and spiking six guns.

Crofton reported that the French buried the English dead with full military honors with both the fort and the British firing salutes.

[d] In 1847 the Admiralty authorized the issuance of the Naval General Service Medal with clasp "Guadaloupe" to all still surviving participants of that campaign.

At the time of the capture, Ballahoo had two of her cannon stored below deck to lower her center of gravity in bad weather, and a crew of thirteen men.
