Monument to Duque de Caxias, Military monument in Praça Princesa Isabel, São Paulo, Brazil.

The Monument to Duque de Caxias is an equestrian bronze statue located in Praça Princesa Isabel in São Paulo. The figure sits atop a substantial granite pedestal with architectural features that create different viewing levels for visitors approaching from the square.

The idea arose in 1939 under General Maurício José Cardoso, who led a fundraising campaign among São Paulo residents. An international model competition held from late 1941 drew 30 entrants and was won by Victor Brecheret. The monument was inaugurated only in 1960, five years after Brecheret's death in 1955, and was placed in Praça Princesa Isabel rather than the Anhangabaú valley he preferred.

The granite reliefs carry the monument's narrative: Caxias speaking to the women of Bagé after the gaucho conflict, the Recognition of Humaitá, Caxias with his three generals, the Battle of Itororó, and his burial. In the Itororó panel he is shown sword drawn, saying "Que me sigam os que são brasileiros". Caxias asked that his coffin be carried by six militiamen only, without pomp.

The site sits on a central square in São Paulo with easy access via multiple public transportation options. Visitors can view and walk around the monument freely at any time without needing advance arrangements.

The monument is 48 metres tall, the height of a ten-storey building, and is described as the largest equestrian monument in the world. Brecheret wanted it placed in the Anhangabaú valley so it could be seen from any angle, but it was moved to Praça Princesa Isabel. He died in 1955 and never saw it inaugurated in 1960.
