Cimbrian (native name Zimbar; German:Zimbrisch or Tzimbrisch; Italian:Cimbro) refers to any of several local Upper German varieties spoken in northeastern Italy. The speakers of the language are known as Zimbern.

Cimbrian is a Germanic language related to Bavarian most probably deriving from a Southern Bavarian dialect (although a Lombardic origin cannot be ruled out). It is also related to the Mócheno language. Its many essential differences in grammar as well as in vocabulary and pronunciation make it practically unintelligible for people speaking Standard German or Bavarian even though Bavarian is spoken in the province of South Tyrol. The use of Italian throughout the country and the influence of nearby Venetian have both had large effects on the number of speakers of Cimbrian throughout past centuries. This effect has been large enough to cause Cimbrian to be deemed by some as an endangered language.
