Abraham Miguel Cardozo (also Cardoso) (c.1630–1706) was a Shabbethaian prophet and physician born in Spain. A descendant of the Maranos in the Portuguese city of Celorico, he studied medicine together with his brother Fernando Isaac, and while the latter was given to his studies, Michael spent his time in singing serenades under ladies' balconies. After having completed his education, he left Spain for Venice.
