HMS Redbreast was a 12 gun Archer-class brig of the British Royal Navy. She operated in the channel until 1808, when she took part in the Baltic expedition. Detachments from her crew and other ships manned two gunboats in August 1808 on the Jade and Weser rivers where they captured a Danish privateer, Mosin, and a Dutch gunboat. In 1811 she was part of a squadron sent to support a Russian attack on Fort Napoleon at Cuxhaven.In 1814 the ship was rerated as a sloop, so that her captain since 1808, Sir George Mouat Keith, could continue to command her on his promotion from lieutenant to commander.
