Cornelis Symonsz van der Schalcke, or Schalcken, was a Dutch Golden Age landscape painter.

He was born in Haarlem as the son of Abraham Cornelisz van der Schalcken who was a sergeant in the Haarlem schutterij. Like his father before him, Cornelis became koster of the Grote Kerk, Haarlem in 1636 and got married there on 13 March 1640 with Janneke Beuns. They had 7 children (2 daughters and 5 sons), but none of them became artists. His earliest work is dated 1644. He was a follower of Pieter de Molijn and Jan van Goyen and died in Haarlem.
