 HDMS Lougen was a Danish naval brig launched in 1805. She saw service in the Danish navy and participated in two notable actions against the British Royal Navy during the Gunboat War. In 1814 as a result of the Treaty of Kiel the Danes transferred her to the Norwegian navy. The Norwegians sold her to German merchants in the Scheld in 1825. She was finally shipwrecked near Bremerhafen in 1881.
