Opalenica (German Opalenitza, German-nazi 1943-45 Oppenbach) is a town in Nowy Tomyśl County, Greater Poland Voivodeship, Poland, with 9,861 inhabitants (2007).
The noble de Opalenica Opaliński (also de Bnin Opaliński) family originated here as lords of the area and a branch of the de Bnin Bniński family of Clan Łodzia.
There was a narrow-gauge railway in Opalenica but it closed and was then dismantled to make way for a motorway that was going to cross the line further away from the town so there was no point in keeping the track in place because there was not going to be any chance of anyone reopening the railway line once the route was blocked by the motorway embankment.
The Portugal National Football Team was based here during the European Championships of 2012 held in Poland and Ukraine.
