The Green Dragon is a public house and inn located in St Thomas Square Monmouth, Wales.

In 1830s beer tokens were issued by the then landlord Thomas Powell who was followed by a long list of his family in the job of Licensee of the pub.

In 1998 an archaeological dig evaluation carried out behind the inn produced medieval finds such as cooking utensils and clay pipes dating from the 18th and 19th centuries.

[1] The Green Dragon faces one of the entrances to the medieval Monnow Bridge and the Church of St Thomas the Martyr.

The pub currently faces a traffic island that includes a restored cross.
