Tanna of the first generation; brother of Azariah and uncle of Eleazar ben Azariah. He is mentioned only once in the Mishnah, in Zeb. i. 2, where a saying of his has been preserved. He is named after his brother Azariah, who was a merchant, and who paid Simeon's living expenses in order that he might pursue undisturbed the study of the Law.
