The Pinsk Marshes (Russian: Пинские болота) or Pripyat Marshes (Pripet Marshes, Russian: Припятские болота) are a vast natural region of wetlands along the Pripyat River and its tributaries from Brest, Belarus (west) to Mogilev (northeast) and Kiev (southeast).

The Pinsk Marshes mostly lie within the Polesian Lowland and occupy most of the southern part of Belarus and the north-west of Ukraine. They cover roughly 38,000 square miles (98,400 km²) surrounding the Pripyat River on both sides. Dense woods are interspersed with numerous swamps, moors, ponds and streams extending 300 miles (480 km) west to east and 140 miles (225 km) north to south. The marshes undergo substantial changes in size during the year, with melting snows in springtime and autumn rainfall causing extensive flooding as the river overflows. Drainage of the eastern portion began in 1870, and significant areas have been cleared for pasture and farmland.

There is a story that the early Slavs hid out from predators in the Pripet Marshes by breathing through reeds.

Pinsk (Belarusian: Пінск, Pinsk; Ukrainian: Пинськ, Pyns'k; Russian: Пинск, Pinsk; Polish: Pińsk; Yiddish/Hebrew: פינסק, Pinsk), a town in Belarus, in the Polesia region, traversed by the river Pripyat, at the confluence of the Strumen and Pina rivers. The region was known as the Marsh of Pinsk. It is a fertile agricultural center. It lies south-west of Minsk. The population is about 130,000. The city is a small industrial center producing ships sailing the local rivers.

The historic city has a beautifully restored downtown full of two-story buildings dating from the 19th century and the beginning of the 20th century. The downtown of this peaceful city has become an active place for youth of all ages with summer theme parks and a newly built soccer stadium that houses the town's soccer team, FC Volna Pinsk.

Pinsk is first mentioned in the chronicles of 1097 as Pinesk, a town belonging to Sviatopolk of Turau. The name is derived from the river Pina. Pinsk's early history is closely linked with the history of Turau. Until the mid-12th century Pinsk was the seat of Sviatopolk's descendants, but a cadet line of the same family established their own seat at Pinsk after the Mongol invasion of Rus in 1239.
