George Vaughan Maddox (1802–27 February 1864) was a nineteenth-century British architect and builder, whose work was undertaken principally in the town of Monmouth, Wales, and in the wider county. Working mainly in a Neo-Classical style, his extensive output made a significant contribution to the Monmouth townscape. The architectural historian John Newman writes that his buildings "give(.) Monmouth its particular architectural flavour. For two decades from the mid-1820s he put up a sequence of public buildings and private houses in the town, in a style deft, cultured, and only occasionally unresolved." The Market Hall and 1-6 Priory Street are considered Maddox's "most important projects".
