Alon Harel (Hebrew: אלון הראל; born 1957) is a law professor at the Hebrew University of Jerusalem, where he holds the Phillip P. Mizock & Estelle Mizock Chair in Administrative and Criminal Law.

His articles often undertake philosophical and legal issues of contemporary political relevance.

A leading advocate of Israeli human rights in Israel, Harel has served on the board of directors of the Association for Civil Rights in Israel, and submitted a Brief on Behalf of Conscientious Objectors to the Israeli Supreme Court.

Harel is the founder and editor of the journal Jerusalem Review of Legal Studies, together with David Enoch.

In 2015, Harel drew criticism for degrading a right-wing student on his Facebook page, tagging her in a post and suggesting that she "return to first grade civics lessons."
