John Churchill, Marquess of Blandford (13 February 1686 – 20 February 1703), sometimes called Charles Churchill, was an English nobleman. He was the heir apparent to the dukedom of Marlborough – as the only surviving son of John Churchill, 1st Duke of Marlborough, an accomplished general, and Sarah Churchill, Duchess of Marlborough, a close friend of Queen Anne. Blandford died childless in 1703, and upon his father's death in 1722, the dukedom passed to his eldest sister, Lady Henrietta Godolphin (née Churchill).
