Jan Janszoon de Heem (bapt. 2 July 1650, Antwerp – after 1695) was a Dutch Golden Age still-life painter and the son of Jan Davidszoon de Heem (1606–1684) and the half-brother of Cornelis de Heem (1631–1995). This family of still-life specialists, of which father Jan Davidszoon de Heem is the most significant, had a strong impact on the genre throughout the north and south Netherlands. Jan was baptised in Antwerp on 2 July 1650, but was trained by his father in Utrecht. His works, in fact, are nearly indistinguishable from his father's, and the fact that they both signed them as J de Heem have meant that many paintings in major collections attributed to Jan Davidszoon are actually by Jan Janszoon.
