12–16 Church Street in Monmouth, Wales, is a row of three shop houses designed by the architect George Vaughan Maddox and constructed c. 1837. They form part of Maddox's redevelopment of the centre of Monmouth and stand on Church Street, to the rear of Maddox's Priory Street. The architectural historian John Newman has written that Maddox's work "gives Monmouth its particular architectural flavour" and Cadw describes the grouping of 12–16 Church Street as "the best preserved early 19th century shopfront in Monmouth."
