Jan Jansz. Vos (baptised 4 March 1612 in Amsterdam – buried 12 July 1667 in Amsterdam) was a Dutch playwright and poet. A glassmaker by trade (in that position he provided all windows for the new city hall on the Dam), he also played an important role as stage-manager and director of the theatre. He organized, on the mayors' orders, processions and splendid decorated floats, which sometimes drew disapproval, criticism, and derision.
