Hunsrik (natively Hunsrik [ˈhunsɾɪk], Hunsrückisch or Hunsrickisch and Portuguese hunsriqueano or hunsriqueano riograndense), also called Riograndese Hunsrik, Riograndenser Hunsrückisch or Katharinensisch, is a Moselle Franconian language derived primarily from the Hunsrückisch dialect of West Central German which is spoken in parts of South America. A co-official language in the Brazilian municipalities of Antônio Carlos, Santa Maria do Herval, and São João do Oeste, Hunsrik is spoken in the states of Rio Grande do Sul, Santa Catarina, and Paraná, as well as some regions of neighboring Paraguay and Argentina. It has been an integral part of the historical and cultural heritage of the Brazilian state of Rio Grande do Sul since 2012, and considered an intangible cultural heritage of Santa Catarina state since 2016.
Hunsrik developed from the Hunsrückisch dialect spoken by immigrants from the Hunsrück region of Germany (Rhineland-Palatinate, Saarland) who settled in Brazil's southern region such as Rio Grande do Sul, beginning under the Empire of Brazil in 1824. This immigration later fell under the control of individual states, and then of private European investment enterprises. While primarily based on the Hunsrückisch branch of the German language, it has also been greatly influenced by other German dialects such as East Pomeranian and Plautdietsch and by Portuguese, the national language of Brazil. It has been influenced to a lesser extent by indigenous languages such as Kaingang and Guarani and by immigrant languages such as Italian and Talian.
