The Church of St David is a parish church in Llanddewi Rhydderch, Monmouthshire, Wales, with origins in the 12th century; the tower base may date from this time.

The fabric of the current building is 14th–15th century in date, with a Victorian restoration by John Pollard Seddon in 1862 and 1863.

The origins of the building are Norman, with the base of the tower,[1] and some of its lancet windows appearing to date from this time.

The building comprises a nave, chancel, porch and a tower with a "pyramidal cap of "typical Border design".

[2] The church is a Grade II* listed building, its listing record describing it as a "medieval church sensitively restored".
