Avraham Moshe Bonhardt of Peshischa (Yiddish: אברהם משה בונהרט פון פשיסכע; c. 1800 – December 27, 1829) also known as the Illui Hakudosh (lit. 'The Holy Prodigy') was the contested third Grand Rabbi of Peshischa, succeeding his father R. Simcha Bunim Bonhardt of Peshischa, after his father's death in 1827. He led the less radical sect of Peshischa for two years, until his death in 1829, after which his followers adopted R. Israel Yitzhak Kalish of Vurka as his successor.
