Gillis van Valckenborch or Egidius van Valckenborch (Antwerp 1570 – Frankfurt am Main, end March or 1 April 1622) was a Flemish painter and draughtsman who spent most of his career in Germany. He was a member of the van Valckenborch dynasty of painters who painted mainly landscapes. Unlike his family members, he is mainly known for his large-scale compositions with many swirling figures depicting scenes from ancient history or mythology. While his landscape drawings evidence his interest in landscape art no landscape paintings have been attributed to him.
