Meänkieli (lit. "our language") is the name used in Sweden for Finnish dialects spoken in the northernmost parts of the country around the valley of the Torne River.

Linguistically, Meänkieli consists of two dialect sub-groups (Tornio and Jällivaara dialects) of the Peräpohjola dialects, which belong to the Western dialects of Finnish. For political and historical reasons it has the status of a minority language in Sweden. In Swedish nowadays, the language is usually referred to as Meänkieli by the authorities; a common, and older, name is tornedalsfinska which literally means "Torne Valley Finnish". Meänkieli refers to Torne Valley Finnish (also spoken on the Finnish side of the Torne River) and the Gällivare dialects which belong to the much larger Peräpohjola dialect group (see Dialect chart).

Meänkieli is chiefly distinguished from standard Finnish by a lack of influence from modern 19th and 20th century developments in that language. Meänkieli also contains many loanwords from Swedish pertaining to daily life. However, the frequency of loanwords is not exceptionally high when compared to some other Finnish dialects: for example the dialect of Rauma has roughly as many loanwords as Meänkieli. Meänkieli lacks two of the grammatical cases used in standard Finnish - the comitative and the instructive (they are used mostly in literary, official language in Finland). In Finland, Meänkieli is generally seen as a dialect of Northern Finnish. There is also a dialect of Meänkieli spoken around Gällivare which differs even more from standard Finnish.
