Monte Partido (also known as San Miguel del Monte) is a partido in the eastern part of Buenos Aires Province in Argentina.

The provincial subdivision has a population of about 17,500 inhabitants in an area of 1,847 km2 (713 sq mi), and its capital city is Monte, 110 km (68 mi) from Buenos Aires on the banks of the Salado River.

The northwest course of the Salado borders with the Partidos of Roque Pérez and General Belgrano.

Monte lies in the Humid Pampa, a flat rich-soiled agricultural zone.

Drainage is insufficient due to the minimal sloping of the land which causes frequent floods in the area.
