Paso del Rey (King's Ford) takes its name from the estancia (ranch) owned by Senator Amancio Jacinto Alcorta: Estancia Paso del Rey.

The surrounding area was well-known since colonial times because there was a ford which provided a useful crossing place to get the west bank of the Reconquista River.

In fact, Charles Darwin could have crossed the ford in his journey from Buenos Aires to Luján on 27 September 1833 (the only alternative crossing was a wooden bridge known as Puente de Márquez, 4.5 km north).

Paso del Rey is bordered by Moreno City (west), Trujui (north) and Merlo and Reconquista River (south).
