Byalynichy (Belarusian: Бялынічы, romanized: Bialyničy; Russian: Белыничи, romanized: Belynichi; Polish: Białynicze) is a town in Mogilev Region, Belarus. It is located 45 kilometres (28 mi) west-northwest of Mogilev, and serves as the administrative center of Byalynichy District. As of 2024, it has a population of 9,670.

Around 780 Jews lived in Byalynichy at the eve of World War II. They composed about 24 percent of the total population. The Jews were mainly traders.

Byalynichy was under German military occupation from 6 July 1941 until 29 June 1944. 150 Jewish men were killed during an Aktion in September 1941. The remaining Jews, together with Jewish families from nearby settlements in the district, were resettled in a ghetto in the town.

On 12 December 1941, the Germans liquidated the ghetto, with the German Security Police and local Belarusian police gathering the remaining 600 Jews. Those Jews, who were mainly women, children and the elderly, were escorted to the woods and shot in pits that were dug in advance.

The Red Army liberated Byalynichy on 29 June 1944.

In 2016, Byalynichy received the status of town of district subordination (previously it was an urban-type settlement).
