Lake Narach (Belarusian: На́рач, Narač pronounced [ˈnarat͡ʂ]; Russian: На́рочь, Naročj; Lithuanian: Narutis, Naročius, Polish: Narocz) is a lake in northwestern Belarus (Myadzyel District, Minsk Region), located in the basin of the Viliya river.

The shore and islets are nested by different birds, such as the mute swan, fish hawk, tarrock and dabchick.

[2] Archaeologists have excavated many burial mounds of the Baltic and Slavic people that lived around Narach.

In 1919, German composer Siegfried Wagner set to music a poem by Günther Holstein (1892-1931) about a military battle, called Nacht am Narocz (Night at lake Narach).

In the 1930s, the fishers of Narach rose against Polish authorities defending their right to exploit the lake.
