Isaac Abendana was a Spanish-born Jewish scholar, translator, and religious leader who became a pioneering figure in Hebrew studies at English universities during the Restoration period. Born into a Marrano family that had been forced to convert from Judaism to Christianity during the Spanish Inquisition, he was the younger brother of Jacob Abendana and the grandson of David Abendana, one of the founders of Amsterdam's first synagogue. He became hakam of the Spanish Portuguese Synagogue in London after his brother died.
