Jan Collaert the Elder or (I), Hans Collaert the Elder or Johannes Collaert was a Flemish printmaker, publisher, draftsman, tapestry designer, glass painter and designer and engraver of swords. He was the founder of a dynasty of engravers that would play a significant role in establishing Antwerp as one of the leading centres for printmaking in Europe in the second half of the 16th century and the early 17th century.

Jan Collaert the Elder was born in Brussels as the son of Jannen (Jan) Collaert. His father was a designer and painter of cartoons for tapestries. Jan likely trained with his father. After a career as a draftsman producing designs for glass makers, tapestry makers and embroiderers in Brussels, he moved sometime before 1563 to Antwerp where he created designs for the local tapestry workshops. He also provided designs for jewelry.

His first dated print was published by Hieronymous Cock (1518–1570) in 1555. Collaert engraved plates to the designs by other artists for several print publishers in Antwerp during the 1570s. He married Anna van der Heyden, with whom he had four children: Adriaen (c. 1555/65 – 1618)., Hansken (Jan or Hans) (1561 – 1620/1628), Tanneken and Susanna.

The sons would later work in the workshop of Philip Galle and marry Galle's daughters. The workshops of the Collaert and Galle families were close together and their works are hard to distinguish.

He died in Antwerp in October 1580.
