The Nursery (Dutch: De Kraamkamer) is a 1660s oil-canvas painting by Gerard Dou, depicting an allegory on the education of art. In the 17th and 18th century, the triptych was considered Dou's masterwork, and one of the best Dutch Golden Age paintings. The painting went lost when the merchant ship Vrouw Maria sank in the Finnish outer archipelago on 9 October 1771. A copy by Willem Joseph Laquy (1738–1798) in the Rijksmuseum collection gives an impression how the painting may have looked like.
