Kolonja Izaaka (Kolonia Isaaka, Isakowa, קולוניה איזאקה) was a small Jewish farming village in what is now Belarus, founded in 1849 through government land grants to 26 poor Jewish families for the purpose of engaging in agriculture.

The community was founded 1.5 km southwest of the town of Odelsk,[3] then part of Grodno Governorate.

The community at Kolonja Izaaka survived through growing various crops, including grains, legumes, orchard fruits, and by raising bees for honey.

[5] In 1934, Salomon Salit, a Jewish PhD student in agrarian economics at the University of Warsaw, published a dissertation about Kolonja Izaaka.

In 1946 the colony was liquidated together with the nearby settlement of Charnavshchyzna (Belarusian: Чарнаўшчызна) due to the newly formed border between the People's Republic of Poland and the Soviet Union passing there.
