Pieter Nason (Amsterdam, c. 1612 - The Hague, 1688/90) was a Dutch painter. He became a member of The Hague's Sint-Lucas guild in 1639 and one of the 47 members who founded the Confrerie Pictura in 1656. He was possibly a pupil of Jan van Ravesteyn and it is believed that his name was removed from paintings first assigned to Mierevelt, Moreelse and certainly Ravesteyn. It is certain that he painted portraits of Johan Maurits van Nassau-Siegen and King Charles II of England. The date of his death is not known but he died elderly.
