Debrzno [ˈdɛbʐnɔ] (historically: Frydląd Pomorski; Kashubian: Frédląd, Fréląd, or Frëdląd; German: Preußisch Friedland)[2] is a town in Pomeranian Voivodeship, Poland.

The town was mentioned as Fredeland in a document of 1346, when the manager of the Teutonic Order in Człuchów assigned four Hufen territory to Tylo.

During the Napoleonic era, Preußisch Friedland suffered a lot, especially in 1806 and 1807, as French soldiers constantly marched through the town and caused an oppressive rise in prices.

After World War I, the economic situation deteriorated dramatically as the loss of the province of West Prussia meant that the town was now located on the border with Poland.

Towards the end of World War II, Red Army troops entered Preussisch Friedland on 29 January 1945 but were repulsed.
