János Thurzó ({{langx|hu|Thurzó János}}, {{langx|de|Johann T(h)urzo}}, {{langx|pl|Jan Turzo}}, {{langx|sk|Ján T(h)urzo}}; 30 April 1437 in Levoča (Lewscen in 15th century) – 10 October 1508 in Nagybánya) was a Hungarian entrepreneur and mining engineer. From 1477 until his death he was an Alderman (a member of the city council) of Kraków, Poland, and even became its mayor for a while.

By establishing "The Common Hungarian Trade" ({{langx|de|Gemeine Ungarische Handel}}, also known as Fugger–Thurzo company), he developed a very profitable business relationship with Jakob Fugger,{{cite book |first=Kayo |last=Hirakawa |url=https://books.google.com/books?id=fJ-dQpbfrysC&dq=Thurz%C3%B3+family&pg=PA48 |title=The Pictorialization of Dürer's Drawings in Northern Europe in the Sixteenth and Seventeenth Centuries |page=48 |publisher=Peter Lang |year=2009 |isbn=978-3-03911-725-3 }} which held a de facto monopoly over copper mining and trade in the Holy Roman Empire around 1500.

Thurzo first married Ursula Boehm and the couple had three sons: György Thurzó who married Anna Fugger, later György Thurzó became the mayor of Kraków; another son of János, became the archbishop of Breslau (today Wroclaw); and their third son became the bishop of Olomouc.

His second marriage was with Barbara Beck: their daughter Katharina married Johann Jakob Fugger.
