Niterói City Council building, Municipal council building in Niterói, Brazil.

Niterói City Council building is a municipal administration structure featuring eclectic architecture in downtown Niterói. The white facade displays symmetrical windows and varied design elements reflecting early 20th-century characteristics.

The building was designed as the seat of the Legislative Assembly of the State of Rio de Janeiro, built by the firm Meanda Curty and inaugurated on 1 August 1917. It served that role until 1975, when the fusion of the states of Guanabara and Rio de Janeiro moved the state capital to Rio de Janeiro; Niterói's city council then took over the building. On 26 January 1983 it was listed by INEPAC together with the Praça da República ensemble.

The building forms part of the civic centre of Praça da República, alongside the police station, the courthouse, Liceu Nilo Peçanha and the state library. In the entrance hall hang four panels painted by Niterói-born artist Antônio Parreiras, a former state deputy, depicting celebrated moments in the history of Rio de Janeiro state.

The building is located at Praça da República and is easily accessible by public transportation. It sits alongside other government structures, making it simple to orient yourself in the area.

The main facade copies a Roman temple, with six columns and a plain triangular pediment where the Rio de Janeiro state coat of arms is now painted, replacing an earlier high-relief version. At street level, two cement lions sit back to back on pedestals, facing opposite directions to mark the two horizons and the sun's path.
