Harvard Business School (HBS) is one of the graduate schools of Harvard University.

Official name: Harvard University Graduate School of Business Administration: George F. Baker Foundation

The School was founded in 1908 with an initial class of 59 students. Its first location was in Cambridge, Massachusetts.

In the 1920s, the class size reached 500 students. In 1927, the School moved across the Charles River to its present location in Boston - hence the custom of faculty and students of referring to the rest of Harvard University as "across the river."

The school offers a full-time MBA program, a Doctoral program and several executive education programs. Current MBA classes have a size of approximately 880 students. Teaching is almost exclusively done through case teaching (also referred to as the Socratic method), where the students prepare teaching cases and discuss them in class. The School owns the Harvard Business School Press, which publishes business books, teaching cases and the monthly Harvard Business Review.

Current and past faculty members include:
