The River Nevern (Welsh: Afon Nyfer) is a river in North Pembrokeshire, West Wales which runs into St George's Channel. Its length is about 11 miles (18 km).
The source of the river is a spring on the southwest slope of Frenni Fawr, northeast of Crymych. It flows southwest for a short distance, then northward and then generally westward, skirting the northern slopes of the Preseli Hills.
Principal tributaries are Afon Bannon (L - i.e. left, facing downstream), Afon Brynberian (L) and Nant Duad (R).
The river is bridged by several lanes and the B4329 Eglwyswrw to Crosswell road before passing beneath the A487 at Felindre Farchog. It is bridged by the B4582 at the Grade II-listed Nevern Bridge, then winds along wooded valleys until reaching its estuary at Newport, where it is bridged for the final time at Feidr Pen-y-Bont. The river discharges into the sea at Newport's old port area of Parrog, where it is possible to ford the river on foot, with caution, at low tide.

Nevern (Welsh: Nanhyfer) is a small village or hamlet, of just a few houses in Pembrokeshire, West Wales which, together with the adjacent settlements of Felindre Farchog, Monington, Moylgrove and Bayvil, constitutes the community of Nevern. It lies in the valley of the River Nevern close to the Preseli Hills of the Pembrokeshire Coast National Park 2 miles (3 km) east of Newport.
The Norman church of St Brynach is on the site of St Brynach's 6th century "clas", an important ecclesiastical centre. At the time when it is said that Dyfed had seven bishops, this was probably the seat of one. Except for the castellated tower, perilously undercut by the adjacent river Caman, most of the original Norman structure of the present building has been rebuilt. The church and churchyard are remarkable for the Celtic Cross and several inscribed stones.
The Nevern Cross on the south side of the church dates from the 10th century or early 11th century. It consists of two sections fitted together with a mortice and tenon joint, both cut from the local dolerite stone. It has classic braided decorations and inscriptions reading "dns" on one side and "h.an.eh" on the other.
