Expressway S6 (in Polish droga ekspresowa S6) is a Polish highway which has been planned to run from the A6 autostrada near Szczecin, through Koszalin to Gdańsk, parallel to the Baltic coast, forming the main connection between Gdańsk and Szczecin.

As of 2025, the sections from Szczecin to Słupsk and from Bożepole Wielkie to Gdańsk are open. The remaining part from Słupsk to Bożepole Wielkie is under construction and is due to open in the first quarter of 2026.

Upon completion of the ongoing contracts in 2026, A6/S6 will be open on its entire intended route from the German border to Gdańsk. Later, a new route of S6 will be constructed to form the western bypass of Szczecin, providing a parallel alternative to the existing route of A6 and S6 south-east of Szczecin.
