Sar Shalom ben Abraham (Hebrew: שר שלום בן אברהם) was the head of the remnant of the Palestinian Gaonate in Damascus around the end of the 12th century.
[1][2] When Benjamin of Tudela visited Damascus in around 1168 he found Sar Shalom as Av Beit Din and his brother Ezra as Gaon.
[3] A letter from the Iraqi Gaon Samuel ben Ali from 1191 mentions Sar Shalom as Av Beit Din.
[5][6] Mann disagreed and read the letter as saying Sar Shalom was alive as Av Beit Din under a nephew of his, a son of his brother Ezra.
[7] Sar Shalom is explicitly mentioned as Gaon in a copy of a commentary of the Karaite scholar Yefet ben Eli.
