Krynica Morska [krɨˈɲit͡sa ˈmɔrska] (German: Kahlberg) is a town and coextensive municipality (gmina) on the Vistula Spit in northern Poland with 1,172 inhabitants as of 2023.

[1] Krynica Morska is the main tourist destination on the Vistula Spit.

The administrative area of the town extends along most of the Polish part of the spit, up to the Russian border, also including a number of other localities such as Przebrno and Piaski (the latter being about 4 kilometres (2 miles) from the border, which is not crossable at present).

Because of the inclusion of mainly rural areas of the spit within its boundaries, it has the lowest population density of any town (miasto) in Poland, with 11.74 persons/km².

Adjacent to it is a small cemetery with a monument to the Soviet soldiers killed in the explosion that destroyed the original building.
