Pirqoi ben Baboi (Hebrew: פירקוי בן באבוי), also written Pirqoi ben Babui, was a Babylonian scholar of the Talmud who lived sometime in the 8th–9th century. He is chiefly remembered for a polemical letter he wrote, addressed to all places in Afriqiya and Sfarad, but thought to be directed in particular to the Qeirwān Jewish community in Tunisia concerning the traditions of Eretz Israel. His writings have been called 'one of the most intriguing Babylonian Jewish texts to have survived the vicissitudes of history'.
