Tarifit (Tarifit: Tmaziɣt, pronounced [θmæzɪχt]; Arabic: الريفية, romanized: ar-rīfīyah), also known as Riffian, is a Zenati Berber language spoken in the Rif region in northern Morocco. It is spoken natively by some 1,200,000 Riffians, comprising 3.2% of the population of Morocco, primarily in the Rif provinces of Nador, Al Hoceima and Driouch.

The traditional autonym of the language is Tmaziɣt (Tamazight), a term that is widely used, albeit in different forms, among Berber speaking groups all over northern Africa. Tarifiyt (pronounced Tarifect in central dialects), as a linguistic term, is a new coinage, developed when it became more and more relevant to distinguish it from other Berber varieties.

Riffian is a Zenati Berber language which consists of various sub-dialects specific to each clan and of which a majority are spoken in the Rif region, a large mountainous area of Northern Morocco, and a minority spoken in the western part of neighbouring Algeria.

Riffian is spoken mainly in the Moroccan Rif on the Mediterranean coast and in the Rif mountains, with a large minority in the Spanish autonomous city of Melilla. There are also speakers of Riffian in Morocco outside the Rif region, notably in the rest of Moroccan cities where they compose a minority. The neighbour state of Algeria is also home to Rif minorities. A Riffian-speaking community exists in the Netherlands and Belgium as well as to a lesser extent other European countries.

There is a large amount of dialectal variation in Riffian Berber; this can easily be seen using the dialect Atlas (Lafkioui, 1997), however Riffian compose a single language with its own phonetical innovations distinct from other Berber languages. Majority of them are spoken in Northern Morocco, this includes the varieties of Al Hoceima, Temsamane, Nador, Ikbadene (including Iznasen) and the more southernly variety in the Taza province. Besides Riffian, two other related and smaller Berber languages are spoken in North Morocco: the Sanhaja de Srair and the Ghomara languages. They are only distantly related to Riffian and are not mutually intelligible with it.

A few Riffian dialects are or used to be in the western part of Algeria, notably by the Beni Snouss tribe of the Tlemcen, as well in Bethioua but also in various colonial districts Riffians started to emigrate to since the 19th century.

There is no consensus on what varieties are considered Riffian and not, the difference of opinion mainly lie in the easternmost dialects of the Iznasen and the westernmost dialects of Senhaja de Sraïr and Ketama. Dialects include West-Riffian (Al Hoceima), Central-Riffian (Nador) and East-Riffian (Berkane). Iznasen (Beni Znassen) is counted as a dialect in Kossman (1999), but Blench (2006) classifies it as one of the closely related Mzab–Wargla languages.

Lafkioui (2020) argues that the Berber varieties of the Rif area (North, Northwest, and Northeast Morocco), – including the varieties of the Senhaja (westernmost group) and of the Iznasen (easternmost group) – form a language continuum with 5 stable core aggregates:
