The population of Newport is 140,100, making it the third-largest city in Wales. According to Census 2001 data the population of the core built-up area was 116,143. The name 'Newport' derives from the fact that Caerleon was the 'old port' on the river Usk, but as ships became bigger, they could no longer navigate the river to Caerleon so a new port/dock was built near where the Riverfront Arts Centre stands today.

The Welsh language name for the city, Casnewydd-ar-Wysg means 'New castle-on-Usk' (this is a shortened version of Castell Newydd ar Wysg). This refers to the twelfth-century castle ruins near the city centre. The original Newport Castle was a small Motte-and-bailey castle in the park opposite St. Woolos Cathedral. It was buried in rubble excavated from the railway tunnels that were dug under Stow Hill in the 1840s and no part of it is currently visible. Newport also has the Latin name Novus Burgus, meaning new borough or new town. It is sometimes labelled Newport-on-Usk on old maps.
