Blenheim is named after the Battle of Blenheim (1704) in the War of the Spanish Succession, where troops led by John Churchill, 1st Duke of Marlborough defeated a combined French and Bavarian force. The New Zealand Ministry for Culture and Heritage gives a translation of "flax stream" for the town's Māori name, Waiharakeke.
