Yosef Mendelevitch (b. 1947 in Riga), was a refusenik from the former Soviet Union, also known as a "Prisoner of Zion" and now a politically unaffiliated rabbi living in Jerusalem who gained fame for his adherence to Judaism and public attempts to emigrate to Israel at a time when it was against the law in the USSR.

Mendelevich was born in Riga and started his Jewish activities in the 1960s. He formed a student group of underground Jewish Education in 1966 and became an editor of an underground newsletter Iton on Jewish issues in 1969. Being repeatably refused the right to immigration, he became one of the leaders of the Dymshits–Kuznetsov hijacking affair, recounted in his 2012 memoir, Unbroken Spirit. As punishment, he was imprisoned for eleven years. During the imprisonment he was punished for keeping Jewish precepts. In 1981, after a worldwide struggle, he was released and immigrated to Israel.
