Barranquenho (Barranquenhu[2]) is a Romance linguistic variety spoken in the Portuguese town of Barrancos, near the Spanish border.

Barranquenho speakers maintain that they speak neither Spanish nor Portuguese but a third language altogether different.

[7] The Portuguese form of the first person of the plural, nós, is replaced by nusotrus - a variation of the Spanish nosotros.

It prefers the Spanish diminutive -ito to the Portuguese -inho, and it typically uses the present subjunctive for future reference, as in quando eli benha 'when he comes'.

[7] On 26 November 2021, the Parliament of Portugal unanimously voted for the approval of a resolution through which Barranquenho was recognized and protected in the municipality.
