Judith Madan (née Cowper; 26 August 1702 – 7 December 1781) was an English poet. She was the granddaughter of the diarist, Sarah, Lady Cowper (1644–1720) and aunt of the poet William Cowper. She was a correspondent, admirer and protégé of Alexander Pope prior to her marriage, and she composed an admired early-gothic work, Abelard to Eloisa, as a response to Pope's Eloisa to Abelard.
