Willem Vorsterman (died 1543) was an early printer of books, active in Antwerp between 1504 and 1543. He published about 400 books in Dutch, Spanish, English, Latin, French and Danish, making him the second most productive printer in the Netherlands in the first half of the 16th century, behind Hillenius. His earliest production, between 1500 and 1520, consisted mainly of works of fiction in Dutch often in chapbook format, while he later expanded into other languages and genres, with more luxurious, illustrated editions. He entered the Antwerp Guild of Saint Luke in 1512 and was its dean in 1527 and 1542. His shop was in the "Golden Unicorn", near the Kammerpoort in Antwerp.
