The Military Academy (AM; Academia Militar in Portuguese) is a Portuguese military establishment, which has the ability to confer educational qualifications equivalent to a university. It develops activities of teaching, research and support for the communities with the purpose of training and forming officers for the Portuguese Army and the Republican National Guard.

The Military Academy has this designation since 1959, but the first such establishment occurred in 1640 when the Military Higher Education was created.

Currently, the Portuguese Military Academy is located in two different barracks, a main one in Lisbon's Bemposta Palace and a detachment in Amadora.
