Wejherowo County is a unit of territorial administration and local government (powiat) in Pomeranian Voivodeship, northern Poland, on the Baltic coast. It came into being on January 1, 1999, as a result of the Polish local government reforms passed in 1998. Its administrative seat and largest town is Wejherowo, which lies north-west of the regional capital Gdansk. The county also contains the towns of Rumia, lying east of Wejherowo, and Reda, east of Wejherowo. Rumia, Reda and Wejherowo are contiguous, and are referred to as the Kashubian Tricity, an allusion to the larger Tricity area centred on Gdansk.
