Harvard Law School (also known as Harvard Law or HLS) is one of the professional graduate schools of Harvard University. Located in Cambridge, Massachusetts, it is the oldest continually-operating law school in the United States and is home to the largest academic law library in the world.

The current Dean of Harvard Law School is Martha Minow, who assumed the role on July 1, 2009. Harvard Law has 246 faculty members. Many are preeminent legal scholars; Harvard Law School faculty were responsible for more papers downloaded on the Social Science Research Network than any other law school, a fact only partially explained by the school's size.
