Jan Gerritsz van Bronckhorst (also Bronchorst or Bronkhorst; 1603–1661) was a Dutch Golden Age painter and engraver.

He is considered today to be a minor member of the Utrecht Caravaggisti.

According to Arnold Houbraken, van Bronckhorst apprenticed as an eleven-year-old with the glass engraver Verburgh in Utrecht.

In 1647 he moved to Amsterdam where he created the stained glass windows and the organ doors (almost the only area in a Calvinist church where figurative painting was sometimes allowed) of the Nieuwe Kerk (finished in 1655).

[citation needed][clarification needed] Unlike his work for churches, his secular paintings show the influence of Caravaggio, and also show a striking appeal to sensuality.
