Sampson d'Artois (also Dartas or Dartasso) (died after 1430) was a French born office holder in fifteenth-century Ireland.
The d'Artois family were originally from Gascony and came to Ireland about 1490 in the service of the English Crown. The most notable member of the family was Sir Jenico d'Artois the elder (died 1426) who was a trusted military commander in the service of three successive Kings of England.
That Sampson was a close relative, most likely a brother, of Jenico is confirmed by Jenico's will, in which he appointed his widow Elizabeth and Sampson as his co-executors. An order of the Privy Council of 1426 released them from any debts they had incurred as executors.
Sampson was appointed Chancellor of the Exchequer of Ireland in 1424; he appointed James Blakeney as his deputy. Blakeney became Chancellor of the Exchequer in 1431, when Sampson presumably either died or retired.
