In the Polish system of local administration, a dzielnica (Polish plural dzielnice) is an administrative subdivision or quarter of a city or town. A dzielnica may have its own elected council (rada dzielnicy, or dzielnica council), and those of Warsaw each have their own mayor (burmistrz). Like the osiedle and solectwo, a dzielnica is an auxiliary unit (jednostka pomocnicza) of a gmina. These units are created by decision of the gmina council, and do not have legal personality in their own right.
