Žmuidzinavičius Museum, commonly known as the Devils' Museum (Lithuanian: Velnių muziejus), is a museum in Kaunas, Lithuania, dedicated to collecting and exhibiting sculptures and carvings of devils from all over the world. As of 2009, its holdings encompass about 3,000 exhibits. The collection was initiated by painter Antanas Žmuidzinavičius (1876–1966). A memorial museum was established in his house after his death. At the time the devil collection had only 260 sculptures. As the collection grew, enriched by a number of gifts presented to the museum by its visitors, a separate three-storey extension was built in 1982. The devils, collected from different cultures, are diverse: some are just works of art, while others are incorporated into useful objects, some represent folk myths, while others express modern political ideas.
