Brazil–Venezuela border


The Brazil–Venezuela border is the limit that separates the territories of Brazil and Venezuela. It was delimited by the Treaty of Limits and River Navigation of May 5, 1859 and ratified by the Protocol of 1929. The geographical boundary begins at the triple point between Brazil-Colombia-Venezuela at Cucuy Rock and continues up the Maturacá channel to the Huá waterfall; it then follows a straight line to the top of a mountain called Cerro Cupi. It then follows the crest of the drainage divide between the Orinoco and Amazon river basins up to the Brazil-Guyana-Venezuela border tripoint on top of Mount Roraima, thus covering a total of 2,199 kilometres and Orinoco ) through the Imeri, Tapirapecó, Curupira and Urucuzeiro mountain ranges, and the Parima, Auari, Urutanim and Pacaraima ranges, in the Guiana Shield.
Historically, Brazil and Venezuela have both made land claims for the western portion of Guyana, referred to as the Guayana Esequiba by Venezuela. The tributaries of the Amazon that extend into Guyana were claimed by Brazil but this was settled during the Pirara arbitration in 1904. The Venezuelan claim to the area is not officially recognized by Brazil, and Guyana exerts effective control over the disputed region.
The internationally recognized border is mostly located in remote and inaccessible wilderness areas, and it has only one road crossing, between the towns of Pacaraima and Santa Elena de Uairén, where the Brazilian BR-174 federal highway from Boa Vista and Manaus joins the Venezuelan Troncal 10 from Ciudad Guayana and Caracas.

History

Venezuelan crisis

In 2018, Roraima, Brazil's northernmost state, experienced a large influx of Venezuelan immigrants along its border. On August 7, the regional government requested that the Supreme [Federal Court of Brazil] close the border, and later that day the Supreme Federal Court denied the request on constitutional grounds.
On February 22, 2019, amid the Venezuelan presidential crisis, President Nicolás Maduro closed the border to prevent international humanitarian aid from reaching Venezuela by land. In May 2019, the Venezuelan government announced the re-opening of the border.
From January 11 to 14, 2025, the border was closed to Venezuelans entering Brazil and Colombia due to conflict over the third inauguration of Nicolás Maduro.
On January 4, 2026, the border was closed to Venezuelans attempting to enter Brazil following the 2026 United States strikes in Venezuela a day prior; however, Brazilians in Venezuela are allowed to cross the border. The Brazilian military is monitoring the border.
