Haines is an English surname of Anglo-Saxon origin. Haines is a patronymic form of the medieval male given name "Hain", itself derived from the Old German "Hagano", originally a byname meaning "hawthorn". This name had existed in England before the Conquest of 1066, but was later popularized by the Normans. Additionally, Haine may be derived from the Old Norse "Haghni" or "Hagne".
