Bartolomé Mitre Martínez (1821-1906) was an Argentine statesman, general, and author. He was president of the republic from 1862 to 1868.

As a liberal, he was an opponent of Juan Manuel de Rosas, and he was forced into exile and worked as a soldier and journalist in Uruguay, Bolivia, Peru, and Chile.

Mitre returned to Argentina after the defeat of Rosas. He was a leader of the revolt of Buenos Aires against Justo José de Urquiza's federal system, and was appointed to important posts in the provincial government after Buenos Aires seceded from the confederation.

Mitre was defeated by Urquiza in the civil war of 1859, and Buenos Aires reentered the Argentine confederation. In October 1862, Mitre was elected president of the republic, and national political unity was finally achieved; a period of internal progress and reform then commenced.

Mitre was also the founder of La Nación one of South America's leading newspapers.

On his passing in 1906, he was interred in La Recoleta Cemetery in Buenos Aires.
