Yadua the Babylonian (Hebrew: ידוע הבבלי‎, translit: Yadua HaBavli) was a 2nd-century tanna of the fifth generation. He was born in Babylonia but subsequently moved to the Land of Israel, becoming the student of Rabbi Meir.^[1][2]

He is mentioned once in the Mishna:

• Yadua the Babylonian said in the name of Rabbi Meir: "If [two dogs came] from one direction they do not count as an unavoidable accident, but if [they came] from two directions they count as an unavoidable accident."^[3]
