St Gwenllwyfo's Church is a 19th-century parish church near the village of Dulas, in Anglesey, Wales. It was built between 1854 and 1856 to replace an earlier church in the parish, also dedicated to St Gwenllwyfo, which needed repair and had become too small for its congregation. The new church was built nearer to the Llys Dulas estate, whose owner contributed £936 towards the total cost of £1,417, rather than near the area where many of the parishioners lived.

The church is still used for worship by the Church in Wales, one of four in the parish of Amlwch. It is a Grade II* listed building, a national designation given to "particularly important buildings of more than special interest", in particular because of its "fine collection" of stained glass.
