Janszoon is Dutch in Origin.

Janszoon is a Dutch patronymic name meaning “son of Jan,” with Jan the Dutch form of John (from Hebrew Yohanan, “God is gracious”). It combines the possessive -s with zoon “son,” a formation common in Middle Dutch naming. As such, Janszoon functions more as a lineage marker than a traditional given name.

The name flourished in the Low Countries during the 16th–17th centuries, typically appended after a man’s given name: Willem Janszoon (often written Jansz), the navigator credited with the first recorded European landfall in Australia; Jan Janszoon, the Dutch corsair later known as Murat Reis; and Abel Janszoon Tasman, explorer of Tasmania and New Zealand. With the decline of patronymics, hereditary surnames crystallized into variants like Jansen, Janssen, Jansz, Janse, and Janssens. Today Janszoon is rare as a first name, occasionally adopted to honor Dutch heritage or used as a distinctive middle name.
