Edmund Ludlow (c. 1617–1692) was an English parliamentarian, best known for his involvement in the execution of Charles I, and for his "Memoirs", which were published posthumously in a rewritten form and which have become a major source for historians of the Wars of the Three Kingdoms. Ludlow was elected a Member of the Long Parliament and served in the Parliamentary armies during the English Civil Wars. After the establishment of the Commonwealth in 1649 he was made second-in-command of Parliament's forces in Ireland, before breaking with Oliver Cromwell over the establishment of the Protectorate. After the Restoration Ludlow went into exile in Switzerland, where he spent much of the rest of his life. Ludlow himself spelled his name Ludlowe.
