Hillel Halkin was born in New York City two months before the outbreak of World War II. He was the son of Abraham S. Halkin, then a professor of Jewish literature, history and culture at the Jewish Theological Seminary of America, and his wife Shulamit, a daughter of Rabbi Meir Bar-Ilan. In 1970 he made aliyah to Israel, settling in Zikhron Ya'akov. He studied English Literature at Columbia University.
Halkin is married to Marcia and is the father of two daughters.
Halkin translates Hebrew and Yiddish literature into English. He has translated Sholem Aleichem's Tevye the Dairyman, and major Hebrew and Israeli novelists, among them Yosef Haim Brenner, S. Y. Agnon, Shulamith Hareven, A. B. Yehoshua, Amos Oz, and Meir Shalev.
Halkin's second book, Across the Sabbath River (2002), is a work of travel literature in which he goes in search of the truth behind the mystery of the Ten Lost Tribes. He became increasingly interested in the Bnei Menashe, who began to immigrate to Israel from India in the late 20th century, and helped to arrange DNA testing in 2003 in Haifa. Since then he has written A Strange Death, a novel based on the local history of Zikhron Ya'akov, where he resides. His intellectual biography of Yehuda Halevi won a 2010 National Jewish Book Award.
In 2014, he published a new biography of Vladimir Jabotinsky.
Halkin writes frequently on Israel and Jewish culture and politics. His articles have been published in Commentary, The New Republic, The Jerusalem Post and other publications. He is a member of the editorial board of the Jewish Review of Books.
