king of the Salian Franks from whom Frankish tradition held the Merovingian dynasty to have taken its name. He was the father of Childeric I (d. 481/482) and grandfather of Clovis I (c. 466–511).

Nothing definite is known of Merovech's life, but an early myth made him the son of a sea god. He is mentioned in Gregory of Tours's Histories and, according to later sources, fought against Attila the Hun at the Battle of the Catalaunian Plains (451).
