Babruysk, Babrujsk, or Bobruisk (Belarusian: Бабру́йск, Łacinka: Babrujsk, Russian: Бобру́йск, Polish: Bobrujsk, Yiddish: באברויסק) is a city in the Mogilev Region of eastern Belarus on the Berezina river. It is a large city in Belarus. As of 2009, its population was 215,092. The name Babruysk (as well as that of the Babruyka River) probably originates from the Belarusian word babyor (бабёр; beaver), many of which used to inhabit the Berezina. However, beavers in the area had been almost eliminated by the end of the 19th century due to hunting and pollution.
