Noroeste Rio-Grandense () was one of the seven Mesoregions on the state of Rio Grande do Sul in Brazil. It included 216 municipalities grouped in thirteen microregions. The IBGE has since discontinued the microregion system for population tracking, replacing it with the term "immediate geographic region" ().
