The Afon Crafnant (English: River Crafnant) is a tributary of the River Conwy (Afon Conwy in Welsh), which is the main river of the Conwy valley in north-west Wales.
It flows from picturesque Llyn Crafnant, joining the river Conwy at Trefriw. It is about 2.5 miles (4.0 km) in length. The river Geirionydd is a tributary which flows from Llyn Geirionydd. They have a confluence a little below the former Klondyke Mill, which used water from both rivers. Klondyke was a mining and milling complex connected with some of the metal mines of the Gwydir Forest.
The Crafnant is also fed by a number of unnamed streams draining from Cefn Cyfarwydd, the ridge to the north-west.
At Trefriw some water from the river is extracted to pass through the Trefriw Woollen Mills to generate hydro-electricity for the machinery, after which the river flows over the Fairy Falls, a popular attraction.
Coed Crafnant, an area of woodland in the valley, is managed by the North Wales Wildlife Trust.
