Maerten van Heemskerck (Heemskerk, 1498 – Haarlem, 1574) was a Dutch painter and draughtsman from North-Holland, who worked in a variety of places, including Haarlem, Amsterdam, Mantua and Rome.

Maerten van Heemskerck began his artistic training in Haarlem with Cornelis Willemsz and later also studied under Jan van Scorel. While in Rome, he focused on Classical Antiquity and the Italian Renaissance, and when he returned to Haarlem, he used his trip as inspiration for many religious, allegorical and mythological paintings. He was also known for his portraits and large-scale production of prints that he himself designed.
