Okonek () is a town in Poland, in Zà Âotów County in Greater Poland Voivodeship, with approximately 4,200 inhabitants.
The settlement was first mentioned in a document of 1547. In 1597, Duke John Frederick established three annual fairs. Due to its location as the sole Ducal Pomeranian customs point on the trade route from Gdaà Âsk and Königsberg to Germany, it developed an urban character. It was granted town rights in 1754. The town suffered in a Russian invasion during the Seven Years' War. The cloth industry flourished until the Napoleonic Wars.
