The National Military College (Spanish: Colegio Militar de la Nación) is the institution in charge of the undergraduate education of officers of the Argentine Army.

Established on October 11, 1869, by President Domingo Sarmiento at the height of the Paraguayan War, its original quarters were opened in where the Parque Tres de Febrero stands today, with Col. Juan F. Czetz as the first superintendent.

It was transferred to San Martín in 1892, and to its present location, the site of the 1852 Battle of Caseros that deposed mid-19th century strongman Juan Manuel de Rosas, in 1938.

For university graduates (in medicine, dentistry, pharmacy, biochemistry, veterinary, law, information technology and physical training) and private aviators.

A system of short courses for reserve officers was established in 2000, but was discontinued after a few years due to the poor performance of the graduates.
