Isaac Samuel Reggio (YaShaR) (Hebrew: יש"ר, יצחק שמואל רג'יו) (August 15, 1784, Gorizia – August 29, 1855, Gorizia) was an Austro-Italian scholar and rabbi. Reggio studied Hebrew and rabbinics under his father, Abraham Vita, later rabbi of Gorizia, acquiring at the same time in the gymnasium a knowledge of secular science and languages. Reggio's father, one of the liberal rabbis who supported Hartwig Wessely, paid special attention to the religious instruction of his son, who displayed unusual aptitude in Hebrew, and at the age of fourteen wrote a metrical dirge on the death of Moses Ḥefeẓ, rabbi of Gorizia.
