A commencement speech or commencement address is a speech given to graduating students, generally at a university, generally in the US, although the term is also used for secondary education institutions. The "commencement" is a ceremony in which degrees or diplomas are conferred upon graduating students. A commencement speech is typically given by a notable figure in the community, during the commencement exercise. The person giving such a speech is known as a commencement speaker. Very commonly, colleges or universities will invite politicians, important citizens, or other noted speakers to come and address the graduating class.
