The Church of St Michael and All Angels is the former parish church of Gwernesney, Monmouthshire, Wales. It is a Grade I listed building. In 2017, the church was vested in the care of the Friends of Friendless Churches.
The church is thirteenth century in origin but with much fifteenth-century work. The double bell gable, and more, was restored in 1853âÂÂ4 by John Pollard Seddon. It is of Old Red Sandstone.
The interior contains a late medieval screen, "of particular interest." The church register of baptisms and burials dates from the year 1758 and that of marriages from 1757.
