Bernacki Most [bɛrˈnat͡ski ˈmɔst] is a village in the administrative district of Gmina Narewka, within Hajnówka County, Podlaskie Voivodeship, in north-eastern Poland, close to the border with Belarus. It lies approximately 6 kilometres (4 mi) west of Narewka, 16 km (10 mi) north-east of Hajnówka, and 46 km (29 mi) south-east of the regional capital Białystok.

It is in one of five Polish/Belarusian bilingual Gmina in Podlaskie Voivodeship regulated by the Act of 6 January 2005 on National and Ethnic Minorities and on the Regional Languages, which permits certain gminas with significant linguistic minorities to introduce a second, auxiliary language to be used in official contexts alongside Polish.
