The Sugambri, Sigambrer or Sicambri were a west Germanic tribe which existed during the time of the Roman Empire. Their original homeland was located in what is now the region of Gelderland in the Netherlands, on the lower Rhine river.

Historians posit that the Sugambri, along with other west-Germanic tribes, eventually became part of the tribal confederation from which stemmed the Franks. Gregory of Tours states that the Frankish leader Clovis, on the occasion of his baptism into the Catholic faith in 496, was referred to as "Sicamber" by the officiating bishop of Rheims, suggesting a link between the Sugambri and Clovis's ancestors (the Merovingian royal house of the Franks).
