The Harvard Law Review is a law review published by an independent student group at Harvard Law School. According to the Journal Citation Reports, the Harvard Law Review's 2015 impact factor of 4.979 placed the journal first out of 143 journals in the category "Law". It is published monthly from November through June, with the November issue dedicated to covering the previous year's term of the Supreme Court of the United States. The journal also publishes the online-only Harvard Law Review Forum, a rolling journal of scholarly responses to the main journal's content. The law review is one of three honors societies at the law school, along with the Harvard Legal Aid Bureau and the Board of Student Advisors. Students who are selected for more than one of these three organizations may only join one.

The Harvard Law Review Association, in conjunction with the Columbia Law Review, the University of Pennsylvania Law Review, and the Yale Law Journal, publishes the Bluebook: A Uniform System of Citation, a widely followed authority for legal citation formats in the United States.
