Tredegar Park (Welsh: Parc Tredegyr) is a community (civil parish) of the city of Newport.

It is named after the nearby park, although the community covers a much smaller area.

The community is bounded by the Ebbw River to the northeast, the Great Western Main Line to the east, Pencarn Lane to the south, and the grounds of Tredegar House to the northwest.

Many new private housing estates have been built around Duffryn.

Until 2022 Tredegar Park was the name of the electoral ward coterminous with the community, surrounded by the Marshfield ward to the south, west and east.
