Humahuaca (Omaguaca) is an extinct and unclassified language of Argentina (Campbell & Grondona 2012). Tribal and possibly dialect divisions were Fiscara Jujuy Ocloya Osa Purmamarca and Tiliar. Mason (1950) proposed that Humahuaca was related to Diaguita (Cacán) and Kunza in a group he called Ataguitan but modern sources leave it unclassified due to a lack of data.
