Wleà  () is a town in Lwówek County, Lower Silesian Voivodeship, in south-western Poland. It is the seat of the administrative district (gmina) called Gmina Wleà Â. , it has a population of 1,759.
Wleà  was established in 1214 by the Silesian duke Henry I the Bearded and his wife Hedwig of Andechs, as part of fragmented medieval Poland. It was located near the Wleà  Castle, one of the oldest castles in Poland, which served as a seat of a castellany that was probably founded in 1108 by Polish ruler Bolesà Âaw III Wrymouth. The castle was expanded in the late 12th and early 13th centuries by Dukes Bolesà Âaw I the Tall and Henry I the Bearded, and Henry I with his wife often stayed in the castle. The name comes from the Polish word waà Â, which means "rampart", referring to its plausible role as a Polish defensive stronghold against possible incursions from Bohemia. In 1215, the Saint Nicholas church was founded. Wleà  was granted town rights before 1261. As a result of further fragmentation of Poland into smaller district principalities, Wleà  formed part of the duchies of Legnica and Jawor.
The town was flooded on 16 September 2024, during the 2024 Central European floods.
