Niemierzyn () is a part of the city of Szczecin, Poland situated on the left bank of Oder river, north-west of the Szczecin Old Town and Downtown.
The locale's designation in the Polish language derives from the Slavic given name Niemir.
The area became part of the Duchy of Poland under its first ruler Mieszko I around 967, and following Poland's fragmentation it formed part of the Duchy of Pomerania. During the Thirty Years' War, the settlement passed to Sweden, formally remaining part of the Holy Roman Empire. Later on, it passed to Prussia, and from 1871 to 1945 it was part of unified Germany, within which it was known as Nemitz.
The abandoned tramdepot at Niemierzyà Âska Street nowadays houses the Museum of Technology and Transport of Szczecin.
