HMS Julia was a British Royal Navy 16-gun brig-sloop of the Seagull class launched in February 1806.

After a fairly uneventful decade-long career she was wrecked at Tristan da Cunha in 1817 with heavy loss of life.

Commander Robert Yarker (occasionally mis-written as Tarker) commissioned Julia in February 1806 for the North Sea.

[2] Watt still commanded Julia on 30 August when he captured a French lugger boat privateer, the Petit Decide, of Martinique.

On 21 May 1809, Julia and Unique were at Basse Terre as part of a squadron under Captain Philip Beaver of Acasta.

Lieutenant Thomas Fellowes, captain of Unique, then led a party of 24 men ashore to spike an enemy battery's guns despite being opposed by a large French regular force; in the attack one man was killed, a midshipman from Julia, and seven men were seriously wounded.

[4] In early June 1809 Cherub and Julia, under Dowers's command, sailed into the anchorage at Basse-Terre to cut out two French frigates lying there under the protection of a fort and some batteries.

[1] Julia was at Portsmouth on 31 July 1812 when the British authorities seized the American ships there and at Spithead on the outbreak of the War of 1812.

[10] Julia was stationed at Ascension Island when Jones in 1817 received orders to sail her to Tristan da Cunha.
