Afon Mynach (Welsh for 'River Mynach', Welsh pronunciation: [ˈmənaχ]) is a river in Ceredigion, Wales.
Its source is at the meeting of two smaller rivers, the Nant Rhuddnant and Afon Myherin. Both of these streams have their sources in lakes high in the Cambrian Mountains:
Afon Mynach is notable for the famous Mynach Falls in the village of Devil's Bridge (Pontarfynach), where the river plunges 90 metres into the gorge of Afon Rheidol. It is also famous for the three bridges built one on top of the other in the same village, the lowest of the three said to be built by the devil, hence the name of the bridge as Devil's Bridge, but most probably built by the monks of Strata Florida.
