The Battle of Landguard Fort or the Attack on Landguard Fort was a battle towards the end of the Second Anglo-Dutch War on 2 July 1667 where a Dutch force attacked Landguard Fort near Felixstowe. It was intended to clear the way for an attack on the English Royal Naval anchorage at Harwich. After repeated attempts the Dutch attack planned by Michiel de Ruyter was repelled and as a result the planned attack on Harwich was abandoned. It was one of the last battles of the war in Europe before the Treaty of Breda was signed.
