Simeon ben Gamliel (I) (Hebrew: שמעון בן גמליאל or רשב"ג הראשון; c. 10 BC – 70 AD) was a Tanna sage and leader of the Jewish people. He served as nasi of the Great Sanhedrin at Jerusalem during the outbreak of the First Jewish–Roman War, succeeding his father in the same office after his father's death in 50 AD and just before the destruction of the Second Temple.
