Kuźnica is a settlement and popular seaside resort in northern Poland, located between Chałupy and Jastarnia on the Hel Peninsula on the southern coast of the Baltic Sea in Puck County, Pomeranian Voivodeship.

[1] Kuźnica was a royal village of the Polish Crown, administratively located in the Puck County in the Pomeranian Voivodeship.

[2] In 1635, in the face of a Polish–Swedish War, Polish King Władysław IV Vasa ordered the construction of the Kazimierzowo sea fort.

During the Swedish invasion of Poland (Deluge) in 1655 the Poles withdrew to Puck, and Kazimierzowo was taken over by the Swedes.

[1] During the German occupation of Poland (World War II), several Poles from Hel were enslaved as forced labour to serve new German colonists in Kuźnica.
