Johann Bussemacher (fl. c. 1580 - 1613) was a German publisher, engraver, art dealer, and bookseller active in Cologne in the late 16th and early 17th centuries. He was trained as a copper engraver in Dusseldorf, where he was born. Around in 1583 he established his own imprint and a publishing concern in Cologne. Bussemacher was for a time the largest and most successful publisher in Cologne. He is commonly associated with producing engraved images of saints and noble personages, but he also issued several maps in conjunction with Matthias Quad.
