Sir John Lethbridge, 1st Baronet (1746–1815), of Whitehall Place, Westminster; Sandhill Park, Somerset; in the parish of Pilton, Devon, and Winkleigh Court, Winkleigh, Devon, was Member of Parliament for Minehead in Somerset from 1806 to 1807. He served as Sheriff of Somerset in 1788–9. In 2010 he was discovered to have been the natural father of Claire Clairmont, and thus the grandfather of Lord Byron's daughter Allegra.
