Monmouth Castle (Welsh: Castell Trefynwy) is a castle close to the centre of the town of Monmouth, the county town of Monmouthshire, on a hill above the River Monnow in south-east Wales.

Once an important border castle, and birthplace of Henry V of England, it stood until the English Civil War when it was damaged and changed hands three times before being slighted to prevent it being fortified again. After partial collapse in 1647, the site was reused and built over by Great Castle House, which became the headquarters and regimental museum of the Royal Monmouthshire Royal Engineers.

It is a Grade I listed building and scheduled monument.
