Lomas del Mirador is a city of the La Matanza Partido in Greater Buenos Aires.

Located outside Buenos Aires along the southwest edge of the General Paz Freeway, the city has a population of 51,488 (INDEC, 2001).

The land where Lomas del Mirador is located was sold by Ezequiel Ramos Mexía to Pablo Pelluse in 1868.

A neighboring property was owned by the descendants of Governor Manuel Dorrego, a key figure in the Argentine Civil Wars of the 19th century, and the city shield would include a red lookout tower in reference to both the town's name and that family's allegiance to the Federalists during the civil wars.

The Provincial Legislature declared Lomas del Mirador a city in 1984.
