Jodocus Badius (or Josse Badius) (1462-1535) was a pioneer of the printing industry.

Sometimes called Badius Ascenslus from the village of Asche, near Brussels, where he was born, he became an eminent printer at Paris. His establishment came to be known as the Prelum Ascensianum. He was also a scholar of considerable repute, had studied at Brussels and Ferrara, and before settling in Paris, had taught Greek for several years at Lyons. He illustrated with notes several of the classics which he printed, and was the author of numerous pieces, amongst which are a life of Thomas a Kempis, and a satire on the follies of women, entitled Navicula Stultarum Mulierum.
