The Sinebrychoff Art Museum, known in Finland as Sinebrychoffin taidemuseo and in Swedish as Konstmuseet Sinebrychoff, is the only museum in the country specializing in works by old European masters. Its collections hold an extensive array of European art spanning from the 14th to the 19th centuries.

The museum was founded in 1921 based on a collection gathered by the Russian brewing family Sinebrychoff. It is located in Helsinki, in a mansion at Bulevardi 40, which was built in 1842 by Nikolai Petrovich Sinebrychoff, the first owner of the Sinebrychoff brewery.

On the second floor of the museum, visitors can see the living quarters of Pavel Sinebryukhov and his wife Fanny Gran, which have retained their original furnishings, as well as a miniature cabinet and other art collections. The first floor is used for art exhibitions.

The museum's collections are regularly enriched through private donations, investments, and acquisitions. The oldest donated collection is that of Baron Otto Wilhelm Klinckowström, given to the Finnish Art Society in 1851. Other notable donated collections include those of H.F. Antell, C. Jöle, Yalmar Linde, and Carl von Haartman.

Particular attention in the collection of Pavel and Fanny Sinebryukhov is given to Swedish portraits of the 17th and 18th centuries, as well as Dutch and Flemish paintings of the 17th century.

The museum also features works by Italian, French, German, Spanish, and English masters, such as Lucas Cranach the Elder, Rembrandt, members of the Tiepolo family, Jan van Goyen, and Alexander Roslin, as well as significant collections of graphics and miniatures.
