Coedkernew (Welsh: Coedcernyw) is a community in the south west of the city of Newport, South Wales, in the Marshfield ward. The parish is bounded by Percoed reen to the south, Nant-y-Selsig to the southwest, and Pound Hill to the west. The northern boundary is formed from Gwern-y-cleppa to junction 28 of the M4, then the A48 Cardiff Road. The eastern boundary is formed from the Ebbw River Bridge roundabout to the west of the International Rectifier plant, Duffryn Drive, along the southern edge of Tredegar House country park, Pencarn Lane and Percoed Lane. Despite being a mostly rural parish to the south and west, the north and east is a continuation of the Duffryn built-up area, and has seen large increases in population in recent years due to the continued suburbanisation of Newport; it grew from 574 in 2001 to 2,183 in 2011. This built-up area of Coedkernew forms a crescent around Duffryn and as such, much newly built housing in the Duffryn area actually falls within Coedkernew. This area contains the landmark Coedkernew footbridge over the A48, a large LG plant, three business parks (Imperial Park, Celtic Springs and Cleppa Park), the Patent Office, the Office for National Statistics, Tredegar House, the Celtic Horizons estate and St. Joseph's RC High School. The remains of a prehistoric burial chamber, believed to be neolithic, can be found at the northern boundary near Gwern-y-cleppa . Coedkernew is also considered to be one of the possible sites for early medieval activity in Gwynllwg, as well as a potential site for the church of Gwladys due to its proximity to the abandoned settlement of Pencarn.

Duffryn (Welsh: Dyffryn) is a large housing estate in the southwest of the city of Newport, south Wales comprising a large portion of the Tredegar Park electoral district (ward). Built on land belonging to Tredegar House, it was completed in 1978 and at the time won several awards for its design. The layout of the estate, as viewed from above, is that of large terraces undulating around a central wooded area. Originally a council estate, Duffryn is now a mix of private ownership and Newport City Homes RSL (Registered Social Landlord) properties. The design of the estate is the result of a council competition. It was won by a consortium committed to the theories of planning devised in the architecture department of Cambridge University in the 1960s. The District Amenities Centre that was planned for the south-west corner of the 96-acre site was never built, so the plan of a largely self-sufficient community was not realised.Despite the relative recent development of the estate, the name Duffryn is an ancient name for the wider township of the ancient parish of Bassaleg. There are three secondary schools in Duffryn: John Frost School, St. Joseph's RC High School and the Welsh-medium Ysgol Gyfun Gwent Is Coed. In 2006, John Frost School (known then as Duffryn High School) was the filming location of the Doctor Who episode School Reunion, filmed in late-summer 2005. The majority of the estate is heated by district heating system which is fuelled by biomass.
