Hendrickje Stoffels (1626 – 21 July 1663) was the longtime partner of Rembrandt. The couple were unable to marry because of the financial settlement linked to the will of Rembrandt's deceased wife Saskia, but they remained together until Hendrickje's death. In 1654 she gave birth to Rembrandt's daughter Cornelia. In the later years of their relationship Hendrickje managed Rembrandt's business affairs together with the painter's son Titus.
Hendrickje is widely believed to have modelled for several of Rembrandt's works and to be depicted in some Tronie portraits. However, her role as Rembrandt's model is disputed by some critics.
