Brazo Oriental is a barrio (neighbourhood or district) of Montevideo, the capital of Uruguay.

Brazo Oriental is a residential zone located approximately 5 kilometres (3.1 mi) from Montevideo's centre.

Brazo Oriental borders La Figurita and Jacinto Vera to the south, Bolívar to the east, Cerrito de la Victoria to the northeast, Aires Puros to the northwest and Atahualpa to the west.

It was reported in the press around 1910 that there had been a mortal fight with knives between a "Porteño" (Argentinian) and an "Oriental" (Uruguayan) at the corner of the actual avenues San Martín and Luis Alberto de Herrera.

Although the Argentinian was younger and more agile, the fight was won by the Uruguayan thanks to the power of his arm (brazo).
