Gubin [ˈɡubʲin] (German: Guben) is a town in Krosno Odrzańskie County, Lubusz Voivodeship, in western Poland.

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.

Gubin is situated in the Polish part of the historic Lower Lusatia region, at the confluence of the Neisse and Lubsza rivers.

It starts at the border crossing with Guben, runs to Krosno Odrzańskie and the regional capital Zielona Góra, and further leads to the national road 5 that connects Wrocław and Poznań.

[2] In the early 13th century it was part of the Duchy of Silesia within fragmented Piast-ruled Poland, and it was mentioned under the name Gubin in a document of Duke Henry the Bearded in 1211.

From 1697 in the Polish-Saxon personal union, it was visited by King Augustus II the Strong of Poland and Tsar Peter the Great of Russia.

[3] In 1751, Augustus III of Poland and Saxony established a mint in present-day Gubin, which produced Polish copper coins.

During World War II, in 1944–1945, the Germans operated a subcamp of the Gross-Rosen concentration camp, in which around 1,000 women, most of whom were Jewish, were imprisoned and used as forced labour.

Gubin and its surroundings are the place of cultivation of the gubinka plum, which is named after the town, and is officially recognized by the Ministry of Agriculture and Rural Development of Poland as a traditional product of the area.
