Vyalikaya Myadzvyadka (Belarusian: Вялікая Мядзвядка, romanized: Vialikaja Miadzviadka; Russian: Большая Медвядка, romanized: Bolshaya Medvyadka; Polish: Niedźwiadka Wielka) is a village in Karelichy District, Grodno Region, Belarus.

[2] Historically, the settlement was inhabited by Poles, forming part of the Polish–Lithuanian Commonwealth until 1795, when the third partition of Poland handed over control of the region to the Russian Empire.

It became part of Poland again during the government of the Second Republic between 1918 and 1939, when it was invaded by the Red Army during World War II.

After the end of the war and the formalization of the borders between the countries of the region, the former Niedźwiadka Wielka became part of the Byelorussian Soviet Socialist Republic and, since 1991, the independent state of Belarus.

In 1802, the naturalist Ignacy Domeyko was born on his family's farm, located in present-day Miadzviedka.
