The family de l'Estoile (also spelled as l'Etoile, l'Estoille and Lestoille) was a French family, whose members were noted for their activities in the Safavid Empire (1501-1736). The first known member of the family that moved to Iran was Isaac Boutet de l'Estoille (died 28 July 1667, in New Julfa). He served king Abbas I (r. 1588–1629) as a goldsmith, amongst others.
