Abraham of Suzdal was a 15th-century Eastern Orthodox bishop who served the Suzdal see starting in 1431. He is historically recognized for his role in the Council of Florence in 1439, where he accompanied Metropolitan Isidore. As the sole Russian prelate present at the assembly, he accompanied the monk Simeon to the proceedings. Although he signed the union agreement while facing imprisonment, he later participated in the 1441 council that formally condemned the union.
