Gubin is a town in Krosno Odrzańskie County, Lubusz Voivodeship, in western Poland. It is the administrative seat of the rural Gmina Gubin, though not part of it. Gubin is on the right bank of the Lusatian Neisse river, at the border with Germany. The rail and road border crossings are connected with the German town of Guben, of which Gubin was the central and eastern part until the division of the city by the Oder–Neisse line in 1945.
