Yossi Klein Halevi (born 1953) is an American-born Israeli author and journalist.
Halevi was born and raised in Borough Park, Brooklyn in New York City in a Jewish family. His father was a Hungarian-born Holocaust survivor. After attending high school at Yeshiva University High School for Boys(Brooklyn Branch), he completed a BA in Jewish Studies in Brooklyn College in 1978, and completed his MA in Journalism at Northwestern University. In 1982, he moved to Israel with his wife Sarah (née Lynn Rintoul).
He worked as a senior writer for the bi-weekly magazine The Jerusalem Report from its founding until 2002. Halevi wrote a column for The Jerusalem Post, and wrote regularly on Israeli issues for the op-ed page of the Los Angeles Times, and occasionally for the New York Times and Washington Post. His first book, Memoirs of a Jewish Extremist, was published in 1995. In it, he tells of his youthful attraction to, and subsequent break with, the militant Rabbi Meir Kahane.
In 2001 he published At the Entrance to the Garden of Eden: A Jew's Search for God with Christians and Muslims in the Holy Land. The book tells of his spiritual journey as a religious Jew into the worlds of Christianity and Islam in Israel. Halevi joined the prayers and meditations in mosques and monasteries, in an attempt to experience the devotional lives of his non-Jewish neighbors and to create a religious language of reconciliation among the three monotheistic faiths.
