The Buffel-class monitors were a pair of ironclad monitors built for the Royal Netherlands Navy in the 1860s. They had uneventful careers and were stricken from the Navy List in the late 1890s. Guinea was scrapped in 1897, but Buffel was hulked and converted into an accommodation ship in 1896. She was captured by the Germans during World War II, but survived the war. She became a museum ship in 1979.
