William Caxton (ca. 1415~1422 – ca. March 1492) was an English merchant, diplomat, writer and printer. He is thought to be the first English person to work as a printer and the first to introduce a printing press into England. He was also the first English retailer of printed books (his London contemporaries in the same trade were all Dutch, German or French).

William Caxton's parentage is uncertain. His date of birth is unknown, but records place it in the region of 1415–1424, based on the fact his apprenticeship fees were paid in 1438. Caxton would have been 14 at the date of apprenticeship, but masters often paid the fees late. In the preface to his first printed work, The recuyell of the historyes of Troye, he claims to have been born and educated in the Weald of Kent. Oral tradition in Hadlow claims that Caxton was born there; the same with Tenterden. One of the manors of Hadlow was Caustons, owned by the Caxton family. A house in Hadlow reputed to be the birthplace of William Caxton was dismantled in 1436, and incorporated into a larger house rebuilt in Forest Row, Sussex.
