Monumento a Marechal Deodoro da Fonseca, Historic monument in Centro, Rio de Janeiro, Brazil.

Monumento a Marechal Deodoro da Fonseca is a monument inaugurated on 15 November 1937, sculpted by Modestino Kanto, in Praça Deodoro in central Rio de Janeiro. It holds the remains of Marshal Deodoro da Fonseca and his wife. A bronze equestrian statue stands on a granite pedestal with stone steps, and bronze sculptural groups sit on raised pillars at the four corners.

The monument was inaugurated in 1937 and holds the remains of the marshal who led Brazil's transformation from monarchy to republic in 1889. This installation marks a pivotal moment in the nation's political evolution.

The bronze reliefs on the pedestal show key figures in Brazilian politics who supported the shift from monarchy to republic. These images keep alive the memory of people who shaped the country's direction at a turning point.

The monument sits at a street intersection in Centro and is easy to reach on foot, with space to walk around it and view it from different angles. The area is accessible, though it can be busy during daytime hours.

The monument holds the remains of Marshal Deodoro da Fonseca and his wife, interred within the 1937 work by sculptor Modestino Kanto. In February 2020 the statue of his mother, D. Rosa Paulina da Fonseca, about 2 metres tall and weighing 400 kg, was stolen from the monument.
