San Cayetano is a small town of about 8,000 people in Buenos Aires Province, Argentina.

[1] It is the administrative center for San Cayetano Partido.

In 1903, Victorio de la Canal, whose estancia was named "San Cayetano" after San Cayetano, a Catholic Saint (1480-1547), donated land for a British-owned railway company to build a railroad through the area.

Pedro Nolasco Carrera, a local landowner with considerable political influence, requested permission to found a town near the railway station on his own land, for which official authorization was received from the provincial governor, Inocencio Arias, on 13 March 1911.
