Antonowo-Kolonia (, Podlachian: Antonóvo) is a village in the administrative district of Gmina Orla, within Bielsk County, Podlaskie Voivodeship, in north-eastern Poland. It lies approximately 2 km north-west of Orla, 10 km south-east of Bielsk Podlaski, and 47 km south 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.
