Michael Lerner is an American political activist, the editor of Tikkun, a progressive Jewish interfaith magazine based in Berkeley, California, and the rabbi of Beyt Tikkun Synagogue in Berkeley.

Tikkun is a quarterly interfaith Jewish left-progressive magazine and website, published in the United States, that analyzes American and Israeli culture, politics, religion, and history in the English language. The magazine has consistently published the work of Israeli and Palestinian left-wing intellectuals, but also included book and music reviews, personal essays, and poetry. In 2006 and 2011, the magazine was awarded the Independent Press Award for Best Spiritual Coverage by Utne Reader for its analysis of the inability of many progressives to understand people's yearning for faith, and the American fundamentalists' political influence on the international conflict among religious zealots. The magazine was founded in 1986 by Michael Lerner and his then-wife Nan Fink Gefen. Since 2012, its publisher is Duke University Press. Beyt Tikkun Synagogue, led by Rabbi Michael Lerner, is loosely affiliated with Tikkun magazine. It describes itself as a "hallachic community bound by Jewish law".
