Pieter Jacobsz Duyfhuysen (1608–1677) was a Dutch Golden Age genre painter.
Duyfhuysen was born and died in Rotterdam. According to the RKD he was also known as Colinchovius. He worked in Rotterdam except for a short stay in Haarlem, where he was probably a pupil of Torrentius, during the years 1625-1677.[1]
