Bedwellty House is a Grade II-listed house and gardens in Tredegar, in the Sirhowy Valley in south-east Wales. It was built in the early 19th century on the site of an earlier building and subsequently enlarged into its present form by mid-century. The owners donated the house and its grounds to the public at the beginning of the 20th century. They were restored at the beginning of the 21st century and are open to the public.
