The Monument to Isabella the Catholic (Spanish: Monumento a Isabel la Católica) is an instance of public art located in Madrid, Spain.

A work by Manuel Oms [es], the monument is a sculptural bronze ensemble consisting of an equestrian statue of Isabella of Castile, accompanied by Pedro González de Mendoza and Gonzalo Fernández de Córdoba.

The bronze piece was cast at Nelli's foundry in Rome and it was exhibited in the later city before its transfer to Madrid.

This text was criticised by Pedro de Madrazo in 1883 as lacking in historical rigour, based on issues such as certain events fulfilling the aforementioned "national unity" happening after the death of Isabella in 1504 (the formal independence of Aragon did not come to an end until the death of Ferdinand of Aragon in 1516 or the annexation of Navarre to Castile in 1515).

[4] The ensemble has been also analyzed as an example of a visual representation of a woman tutored (guided in this case) by masculine figures.
