Slutsk is a city in Belarus, located on the Sluch River 105 km (65 mi) south of Minsk. As of 2010, its population is of 61,400. Slutsk is the administrative center of Slutsk District.

Slutsk was first mentioned in writing in 1116. It was part of the Principality of Turov and Pinsk, but in 1160 it became the capital of a separate principality. From 1320-1330 it was part of the domain of the Grand Duchy of Lithuania. Later it was owned by the Olelkovich and Radziwill families, which transformed it into a center of the Polish Reformed Church with a gymnasium and a strong fortress.

Following the 17th century, the city became famous for manufacturing kontusz belts, some of the most expensive and luxurious pieces of garment of the szlachta. Because of the popularity of the cloths made here, belts worn over the zupan were often called of Slutsk despite their real place of origin.

Slutsk was part of Russian Empire after Second Partition of Poland in 1793. It was occupied by Germany in 1918 and by Poland between 1919 and 1920 during Polish Soviet War. In 1920, it was the centre of a major anti-bolshevik uprising known as the Slutsk defence action.

Until World War II and the Slutsk Affair, the city was predominantly Jewish; however, now the population includes no more than 100 Jews. Slutsk was occupied by the German Army on 26 June, 1941, and placed under the administration of Reichskommissariat Ostland. The period of German occupation ended on 30 June, 1944, when troops of the 1st Belorussian Front recaptured the town during the Minsk Offensive of the Red Army.
