The ruins of St Gwenllwyfo's Church stand near Dulas, in the north-east of Anglesey, Wales. The date of construction of the first church on the site is unknown. There was a church here in medieval times: one 19th-century writer suggested that the present building dates from the 15th century and that the font, probably 12th century in date, was the only surviving part of an earlier church on the site. The church (dedicated to Gwenllwyfo, a 7th-century woman about whom nothing else is known) was a chapel of ease attached to the parish of Amlwch, about 5 mi away.

The nave and chancel of the church were not structurally divided, and measure 39 feet 6 inches by 15 feet 9 inches (12 by 4.8 m). Another screen was later added at the west end to stop the wind blowing into the nave, and two windows were added on opposite sides of the chancel. Two box pews were installed during the 18th century, and a bell (now used by the new church) was added. The walls have since been lowered to a height of 5 ft.
