Ivanava (Belarusian: Івáнава, Russian: Ивáново, Polish: Janów Poleski) is a city in the Brest Region of Belarus, an administrative center of the Ivanava district. First mentioned in the 14th century, initially it was a village named Porkhovo. In 1423 it was granted by the king Władysław Jagiełło to the cathedral in Lutsk. Renamed to Janów, in 1465 it was granted with city rights. A small town in Polesia, it shared the fate of the region. On May 16, 1657 it was the seat of the martyrdom of Saint Andrzej Bobola. Annexed by Russia during the Partitions of Poland in 1795, the town did not develop much, mostly because of the proximity of much more populous town of Pinsk. At the end of the 19th century it had circa 3000 inhabitants, mostly peasants and workers in a local minor textile works.
