text: Chuí Stream
  
  The Chuí, or Chuy, Stream (Brazilian Portuguese: Arroio Chuí , Rioplatense Spanish: Arroyo Chuy  or ), is a short stream on the Brazilian–Uruguayan border that is celebrated as Brazil's southernmost point.
  
  Geography
  The Chui rises in a small swamp in the sandy coastal plains of the far southern Brazilian state of Rio Grande do Sul. It runs initially southward, then turns east before flowing into the Atlantic Ocean. In its final course, the stream marks the last stretch of the Brazilian border with Uruguay. In Brazil, it lies mostly in the municipality of Santa Vitória do Palmar, with a short section in Chuí. The Uruguayan side belongs to the city of Chuy, in the department of Rocha.
  
  The Chuí is only a few tens of kilometres long and its water volume is unimpressive; indeed, this is why it is called an arroio or arroyo, which in the local dialects of Brazilian Portuguese and Rioplatense Spanish, respectively, mean "stream." It would be unremarkable, were it not for the fact that it is known throughout Brazil and mentioned in all Brazilian geography schoolbooks as being the country's southernmost point. The precise most southerly point of Brazil is on a bend of the stream approximately  upstream from its mouth, near the twin coastal villages of Barra do Chuí (Brazil) and Barra del Chuy (Uruguay), at .
  
  The mouth of the Chuí Stream is not only the southernmost, but also the westernmost point of the Brazilian coast, as well as both the northernmost and easternmost point of the Uruguayan coast. It also marks the southern end of Cassino Beach, the world's longest uninterrupted stretch of sandy ocean shore, stretching over  from the stone breakwaters of Rio Grande in its northern end.
  
  In popular culture
  The widespread Brazilian Portuguese expression "do Oiapoque ao Chuí" ("from the Oiapoque to the Chuí [rivers]") is used to mean the whole nation, by mentioning the waterways that mark respectively the northern and southern extremities of the Brazilian coastline (the mouth of the Oiapoque River is often mistakenly thought to be the entire country's northernmost point, not only of its coast). The saying is used in the same way as Americans use the expression "from coast to coast."
