HMS Asp was an Acute-class gunbrig (ex-GB No.5), of the British Royal Navy.

In 1798 she participated in Sir Home Popham's failed attack on Ostend.

While she engaged shore batteries four hours in support of a landing by troops she had one seaman killed, and Lieutenant Edmonds was wounded.

[1] Asp and Biter shared in the proceeds of the capture on 18 June 1799 of the galliot Jane.

[1] Because Asp served in the navy's Egyptian campaign between 8 March 1801 and 2 September, her officers and crew qualified for the clasp "Egypt" to the Naval General Service Medal that the Admiralty issued in 1847 to all surviving claimants.
