Jef Vanderveken or Jef Van der Veken (1872 in Antwerp - 1964 in Ixelles) was a Belgian copyist. He mastered the art of reproducing the works of Jan van Eyck and also created, with his banker's funds, the Renders Collection. In 1945 he produced a copy of the stolen Ghent Altarpiece panel The Just Judges.
In 1941, Hermann Göring bought the Renders collection for 300 kilograms of gold, worth about 2 million euros (2003).
