Charles Smith (1715–1762) was an Irish topographer and writer. He was educated at Trinity College, Dublin. He qualified as a doctor and practised as an apothecary in Dungarvan, County Waterford. In the 1730s, along with Walter Harris he discussed a scheme to compile and publish histories of all the Irish counties. The first of these, a history of County Down, jointly edited by Walter Harris and Charles Smith, was printed in 1744. Waterford and Cork followed, but then the society funding the venture broke up, so that he alone carried through the final volume, Kerry, in 1756.
