Jens Andersen Beldenak (deceased 1537) was the son of a shoemaker but managed to become bishop of Funen.

Jens Andersen Beldenak had a fierce temper and did not get along with multiple noblemen. He actually had a falling out with these nobles, and therefore, he turned his bishop's palace into a fortified castle.

King Christian II of Denmark used Jens Andersen Beldenak as a clerical leader during the legal negotiations in Sweden, which led to the Stockholm Bloodbath in 1520.

The movement towards the Reformation made Beldenak resign in 1529, thereby becoming the last Catholic bishop of Funen.
