Johann Veldener, also known as Jan Veldener or Johan Veldenaer; was an early printer in Flanders. He worked as a punchcutter and printer in Cologne, together with William Caxton, who may have financed his first books. They both left for Flanders in 1472. Evidence indicates that Veldener assisted Caxton in setting up his printing office in Bruges and helped printing his first work there, the 1472-1473 Recuyell of the Historyes of Troye by Raoul Lefèvre. Afterwards, Veldener went to Leuven and set up his printing company there, becoming the second printer in Leuven after John of Westphalia, and the third or fourth in the Netherlands. He entered the Leuven University on 30 July 1473 in the faculty of Medicine.
