Portrait of Hendrickje at Window is an oil on canvas painting by the dutch painter and etcher Rembrandt van Rijn. It was painted in 1656-57. Though Rembrandt often treated his faithful mistress Hendrickje Stoffels (1625/26-1663) shabbily, he often portrayed her magnificently. In this canvas, hers is a pensive, possibly Sibylline image, standing at a double door. This painting (86 x 65 cm) is currently housed in the Staatliche Museen, Berlin.
