Abraham ben Judah Leib (Löb) Maskileison (Hebrew: אברהם משכיל לאיתן); (b.1788– d.1848) was a Jewish scholar, rabbi and author active in Russia during the first half of the 19th century.
Born in Radoshkovichy, Maskileison studied under his father Yehuda (Judah) Leib Jaffe (1723–1783), who was av beit din of Khotimsk in Mogilev.
Maskileison discharged his rabbinical duties in many cities, serving as av beit din in Novogrudok.
Having no desire to use his cabalistic knowledge for gain, as was done by the miracle-working rabbis, he devoted his whole life to study of the Torah and the Talmud.
He married Chana (Hanna) Dina, daughter of Aryeh Leib, a scholar and merchant.
