The Battle of Langport took place on 10 July 1645 during the First English Civil War, near Langport in Somerset. Following its success at Naseby in June, the New Model Army under Sir Thomas Fairfax destroyed the last Royalist field army, led by Lord Goring. Parliamentarian victory allowed them to besiege the Royalist port of Bristol, which surrendered in September.
