The River Conwy (Welsh pronunciation: [ˈkɔnʊɨ]; Welsh: Afon Conwy) is a river in north Wales. From its source to its discharge in Conwy Bay it is 55 kilometres (34 mi) long and drains an area of 678 square km.^[2] "Conwy" was formerly anglicised as "Conway."

The name 'Conwy' derives from the old Welsh words cyn (chief) and gwy (water), the river being originally called the 'Cynwy'.^[3][4][5][6]

It rises on the Migneint moor where a number of small streams flow into Llyn Conwy, then flows in a generally northern direction, being joined by the tributaries of the rivers Machno and Afon Lledr before reaching Betws-y-coed, where it is also joined by Llugwy. From Betws-y-coed the river continues to flow north through Llanrwst, Trefriw (where it is joined by the Afon Crafnant) and Dolgarrog (where it is joined by Afon Porth-llwyd and Afon Ddu) before reaching Conwy Bay at Conwy. A local quay, Cei Cae Gwyn, is located on its bank. During spring tides the river is tidal as far as Tan-lan, near Llanrwst.
