Sulmin [ˈsulmin] is a village in the administrative district of Gmina Żukowo, within Kartuzy County, Pomeranian Voivodeship, in northern Poland.

Sulmin was a royal village of the Polish Crown, administratively located in the Gdańsk County in the Pomeranian Voivodeship.

Around that time the factory owner Hartmann from Langfuhr bought the estates of Sulmin, Ottomin, Hochkelpin, Smengorschin and Nestempohl comprising an area of about 30.7 km2 for 1.2 Million Mark for settling purposes.

After it turned out that the military had no need for this terrain, Hartman offered it for sale to the Prussian settling commission for Poznań and West Prussia (Preußische Ansiedlungskommission für Posen und Westpreußen).

The latter organization gradually brought families of Protestant German settlers into the area, most of them being former colonists from Russia, to where they had emigrated a century ago or even earlier and where in recent times they had been subjected to political pressure.
