 In 1217, the town was called "Woynicze".In 1224, another spelling was "Woyniz", and in 1239, "Woynicz".Polish language specialists Kazimierz Rymut and Stanisław Rospond believe that the name Wojnicz comes from the surname "Wojno", which was then changed to "Wojnice", "Wojnic", and finally – Wojnicz.
