The Mexican Army (Spanish: Ejército Mexicano), also known as the National Defense Army, is the combined land and air branch of the Mexican Armed Forces. It includes the Mexican Air Force, the Special Forces Body, and the National Guard.

With an active-duty force of 261,773 servicemembers (as of 2024), the Army is the largest component of the Mexican Armed Forces and among the largest armies in the world. It is under the authority of the Secretariat of National Defense (Spanish: Secretaría de la Defensa Nacional, SEDENA) and is headed by the Secretary of National Defence, who is directly answerable to the President.

The Mexican Army was the first to adopt (1908) and use (1910) a self-loading rifle, the Mondragón rifle.
