Bannow (Irish: Banú) (Yola: Baannough) is a civil parish lying east of Bannow Bay on the south-west coast of County Wexford, Ireland. In modern times the main settlement is the village of Carrig-on-Bannow (or Carrig). In Norman times there was a borough called Bannow on Bannow Island at the mouth of the Bay. This town has since disappeared, probably due to the silting up of the natural harbour channels in the 14th century, and the former island is now attached to the rest of the parish.
