Emilian (Reggiano, Parmesan and Modenese: emigliân; Bolognese: emigliàn; Piacentino: emigliän; Italian: emiliano) is a Gallo-Italic unstandardised language spoken in the historical region of Emilia, which is now in the western part of Emilia-Romagna, Northern Italy.

Emilian has a default word order of subject–verb–object and both grammatical gender (masculine and feminine) and grammatical number (singular and plural). There is a strong T–V distinction, which distinguishes varying levels of politeness, social distance, courtesy, familiarity or insult. The alphabet, largely adapted from the Italian (Tuscan) one, uses a considerable number of diacritics.

Emilian is a Gallo-Italic language. Besides Emilian, the Gallo-Italic family includes Romagnol, Piedmontese, Ligurian and Lombard, all of which maintain a level of mutual intelligibility with Emilian.

The historical and geographical fragmentation of Emilian communities, divided in many local administrations (as signorie then duchies, with reciprocal exchanges of land), has caused a high dialectal fragmentation, to the point the existence of an Emilian koiné has been questioned.
