Pieter Dubordieu (* about 1609 in L'Île-Bouchard, today's Département Indre-et-Loire; after June 4, 1678 probably in Amsterdam) was a Dutch portrait painter of French descent.
Pieter Dubordieu was a little known artist. He was enrolled at Leiden University in 1628 and worked as a painter mainly in Leiden. Although he acquired Amsterdam citizenship in 1636, he can be traced back to Leiden from 1638. There he was a member of the Lukasgilde during the years 1648 to 1651 and 1665 to 1676.
