Barysaw is a city in Belarus located near the Berezina River in the Minsk Region 74 km north-east from Minsk. Its population is around 145,000.

Barysaw is first mentioned in the Laurentian Codex as being founded (as Borisov) in 1102 by the Prince of Polotsk Rogvolod Vseslavich, who had the baptismal name of Boris (the name of the city literally means Boris'). During the next couple of centuries, it was burned and then rebuilt south of its original location.

The town is divided by the river into old and new parts connected by two bridges. The railway station, international road, Ispolkom (ex-KPSS Gorispolkom), military staff headquarters and the central square are in the new part. As usual for this region, families live mostly in flats in large, modern apartment buildings, but there are some single-family homes on the outskirts, some of which do not yet have indoor plumbing. The water comes from an artesian well and is very clean and healthy.

After World War II, Barysaw became a major industrial centre; as of 2002 there are 41 large factories exporting their goods to Russia, the CIS, and worldwide. The railroad is still an important artery, but now it is powered by overhead electric lines.
