Afon Elan (Welsh for 'River Elan') is a tributary of the River Wye which runs through the wide expanse of upland moors, traditionally known as Elenydd, in central Wales.
The name probably arises from elain meaning 'hind' or 'fawn' in reference perhaps to the rushing, bounding nature of its course.
[1] It has its source in wet moorland on the eastern flank of Pen y Deunant in Ceredigion.
It emerges from this chain of reservoirs in a north-easterly direction and passes through Elan Village before turning south-east after 2 miles and making its confluence with the River Wye.
