Fagons was a fifth-rate warship of the Commonwealth of England's naval forces, one of six such ships built under the 1653 Programme. She was built by contract with shipwright Robert Page at his yard at Wivenhoe, Essex, and was launched on 22 May 1654 as a 22-gun Fifth rate. She was named Fagons after the village of St Fagans in Glamorgan, although the Commonwealth dropped the prefix "Saint" from her name.
