Deganwy (Middle Welsh Degannwy, Brythonic *Decantouion) is a village in Conwy County Borough in Wales with a population of 3,700. It is in a more English-speaking region of north Wales, with only 1 in 4 residents speaking Welsh as a first language. It is located south of Llandudno and to the east of Conwy, which is on the opposite side of the River Conwy, and with which it forms the Conwy community. Indeed, the name Deganwy has been interpreted in modern times as Din-Gonwy, which would mean "Fort on the River Conwy", but the historical spellings make it impossible for this to be the actual origin of the name. Deganwy is in the ecclesiastical parish of Llanrhos, and has a Victorian era Gothic parish church dedicated to All Saints.
