Jewish pirates were seafaring Jewish people who engaged in piracy. While there is some mention of the phenomenon in antiquity, especially during the Hasmonean period, most Jewish pirates were Sephardim who operated in the years following the Alhambra Decree ordering the expulsion of Iberia's Jews. Upon fleeing Spain and Portugal, some of these Jews became pirates and turned to attacking the Catholic Empire's shipping as both Barbary corsairs from their refuge in the Ottoman dominions, as well as privateers bearing letters of marque from Spanish rivals such as the United Netherlands.

Samuel Pallache was a Jewish Moroccan merchant, diplomat, and pirate of the Pallache family, who, as envoy, concluded a treaty with the Dutch Republic in 1608. His antecedents fled to Morocco during the Reconquista. Appointed as an agent under the Saadi Sultan Zidan Abu Maali, Pallache traveled to the newly-independent Dutch Republic to discuss diplomatic terms with the Dutch against their mutual enemy, the Spanish. He died in the Netherlands, brought there due to the intervention of his ally, Maurice of Nassau, who helped him when he was arrested by the Spanish.
