The Tarbelli were an Aquitani tribe dwelling in the present-day regions of Labourd and Chalosse, in the west of Aquitania, during the Iron Age.
[6][7] Joaquín Gorrochategui proposed to see the name as the suffix tar- attached to the adjective bel ('black'), which is common in Aquitanian onomastics.
[7] The Tarbelli lived in the regions of Labourd and Chalosse, on both sides of the Adour river.
[8][2] Their territory was located east of the Atlantic Ocean, north of the Vardulli, south of the Cocosates, west of the Tarusates, Atures and Venarni.
[11] Gold extraction and mineral springs brought them a certain wealth, although their main activities remained centred on field and meadow husbandry.
