Aaron ben David Cohen of Ragusa

Aaron ben David Cohen of Ragusa (born about 1580), was a Rabbi in the Republic of Ragusa

His maternal grandfather was Solomon Oheb, also a rabbi in the same city. Aaron studied in his native city and later in Venice, whence he returned to occupy a pulpit in Ragusa. In 1623 he was imprisoned as a supposed accomplice of Isaac Jeshurun, who had been falsely accused of ritual murder.

Rabbi Aaron's sermons, Zeḳan Aharon (Aaron's Beard), together with his grandfather's sermons, Shemen ha-Ṭob (The Good Oil), and the history of Isaac Jeshurun's martyrdom, were published at Venice in 1657, after his death.
