Thielska Galleriet is an art museum in the Djurgården park area of Stockholm, Sweden. The museum originates as the private residence and art gallery of the banker and collector Ernest Thiel (1859-1957) who acquired art by his contemporaries among Scandinavian artists, such as Bruno Liljefors, Eugène Jansson and Edvard Munch. The house, built in 1904-1907, was designed by the architect Ferdinand Boberg. By 1922, Thiel had lost his fortune, and the gallery was acquired by the state in 1924 and opened to the public in 1926.
