Noroeste Rio-Grandense (English: Northwest of Rio Grande) was one of the seven Mesoregions on the state of Rio Grande do Sul in Brazil.

It included 216 municipalities grouped in thirteen microregions.

[1] The IBGE has since discontinued the microregion system for population tracking, replacing it with the term "immediate geographic region" (Brazilian Portuguese: Região geográfica imediata).
