John Reynolds (1625–1657) was a soldier in the English Civil War and during the Commonwealth. Reynolds may have been a member of the Middle Temple. He joined the parliamentary army, and in 1648 he commanded a regiment of horse. He took part in the Cromwellian conquest of Ireland. He was a member of the Westminster-based Protectorate Parliament for Galway and Mayo in 1654 and Waterford and Tipperary in 1656. He was knighted in 1655. In 1657 he commanded the English force which cooperated with the French in Flanders in the Anglo-Spanish War and was lost at sea when returning to England.[1]
