The Naval Flotilla of Alto Uruguay was a flotilla based in Itaqui and operating in Brazil from 1866 to 1906.
In 1874, it became involved in the so-called Alvear Conflict, in which it fired on the neighboring Argentine city of Alvear.

The flotilla was established in 1866 by the Brazilian Empire in Itaqui during the Paraguayan War, in order to prevent Paraguayan invasions of Rio Grande do Sul. It included the Pará-class monitors Alagoas and Rio Grande, as well as some smaller wooden ships. The command of the flotilla was briefly abolished in 1871, being combined with that of the Rio Grande do Sul Flotilla. In 1872, however, Estanisláo Przewodowski, a native of Bahia and of Polish origin, was appointed commander of the flotilla.{{Sfn|Instituto Geográfico e Histórico da Bahia|1907|pp=162–163}}
In 1874, Pamphilo Manoel Freire de Carvalho, a medical lieutenant-captain who had come to the aid of a wounded Brazilian in the nearby Argentine town of Itaqui de Alvear, was assaulted by two healers of Italian origin in front of the local police, who did not react.{{Sfn|Instituto Geográfico e Histórico da Bahia|1907|pp=163–164}} Przewodowski, in reaction, repeatedly asked the Argentine authorities to hand over the aggressors. Seeing no reaction, he ordered on June 22 that both flotilla monitors execute hourly bombardments against the city's outposts, until, at the fourth firing, a committee of Alvear residents went to Itaqui to negotiate a ceasefire, which Przewodowski granted.{{Sfn|Meira|2009|pp=220–221}}{{Sfn|Soares|1995|pp=224–225}}
The flotilla was terminated in 1906.
