Johannes Mytens or Jan Mijtens, or "Mytens" to the English (c.1614 – 24 December 1670) was a Dutch Golden Age painter, almost entirely as a portraitist. Mytens was born in The Hague. According to Houbraken, Johannes (Jan) Mijtens was trained by Anthony van Opstal and later by Nicolas van der Horst. Both of his uncles, and Daniël Mijtens, were painters, and his son Cornelis became an engraver. This statement has often been repeated by various art historians, but unfortunately, Houbraken mixed up his notes on this artist with his notes on Jan Meyssens, the engraver. This Jan Mytens did not have a son Cornelis who was a good engraver. That was Jan Meyssens (and the Meyssens lived in Antwerp, not the Hague).
