Reconquista is a city in the north of the province of Santa Fe, Argentina, 327 km (203 mi) from the provincial capital.

As of 2005, the construction of a road link between the two cities is under study; at present there is no way to cross the multiple minor branches, streams and wetlands except by boat.

Reconquista was founded on 27 April 1872 as a military fort, established by Colonel Manuel Obligado, in lands formerly belonging to the Jesuit mission Reducción San Jerónimo del Rey.

The climate of the region is wet subtropical (average 14 °C (57 °F) in winter, 26 °C (79 °F) in summer), with a mean annual rainfall of 1,290 mm (51 in).

Reconquista was natively inhabited by the Abipones people according to accounts from Jesuit Martin Dobrizhoffer.
