Cornelis van Poelenburgh or Cornelis van Poelenburch (1594 – 12 August 1667), was a Dutch landscape painter and draughtsman. He was the leading representative of the first generation of Dutch landscape painters who were active in Rome in the early 17th century. He was known for small-scale paintings depicting Italianate landscapes with small figures enacting biblical or mythological scenes or in contemporary attire.
His birthplace is unknown. A signed document survives in Utrecht where he is listed as six years old and the son of Simon van Poelenburch, a Catholic canon in Utrecht. He initially trained with Abraham Bloemaert, and his earliest signed paintings are from 1620. He traveled to Rome where he was influenced by Adam Elsheimer and became a founding member of the Bentvueghels, the society of mainly Flemish and Dutch artists working in Rome. The Bentveughels would typically adopt a nickname referred to as the 'bent name'. Van Poelenburch's bentname was ‘satiro’ (‘Satyr’). He counted a few Roman cardinals under his patrons.
He was called to England by Charles I of England, for whom he made small cabinet pieces. He returned to Utrecht where he later died just a few years after his old teacher Abraham Bloemaert.
His "most important and successful" pupils were Daniël Vertangen, Dirck van der Lisse, François Verwilt, and Jan van Haensbergen.Arnold Houbraken claimed that his best pupil was Joan vander Lis from Breda (not Dirk vander Lis from The Hague). Houbraken then mentioned Vertangen, Verwilt, Warnard van Rysen from Bommel, and Willem van Steenree, a nephew. The RKD also mentions Laurens Barata.
