Cors Fochno (Welsh pronunciation: [kɔrs ˈvɔχnɔ]) is a raised peat bog near the village of Borth, in the county of Ceredigion, Wales. Lying on the south side of the Dyfi estuary, it forms a component part of the Dyfi National Nature Reserve. It was designated a UNESCO biosphere reserve in 1976, and is the only such reserve in Wales.[1] A boardwalk leading from the northern edge of the bog skirts the edges of the bog and surrounding woodland.

A significant portion of the 264 hectares (652 acres) former peatland complex was taken for agriculture; the surviving core area supports the largest expanse of primary near-natural raised bog in an estuarine context within the United Kingdom.[2]

Otters, red kites, common buzzards, peregrines and, in the winter,hen harriers can be found here together with a number of Welsh Mountain Ponies,[3] and adder, badger, blackcap, Dartford warbler, fallow deer, nightingale, nightjar, willow warbler, and woodcock. The site holds a population of rosy marsh moth, a very rare species in the UK. The site holds significant populations of Eriophorum angustifolium, the common cottongrass, as well as Round-leaved sundew, all visible from the boardwalk which skirts the northern edge of the bog. In 2019, an extremely rare species of orchid for Great Britain, the Irish Lady's-tresses, was found on the bog.[4] The population has persisted into 2024
