The Berber languages, also known as the Amazigh languages or Tamazight, are a branch of the Afroasiatic language family. They comprise a group of closely related but mostly mutually unintelligible languages spoken by Berber communities, who are indigenous to North Africa. The languages are primarily spoken and not typically written. Historically, they have been written with the ancient Libyco-Berber script, which now exists in the form of Tifinagh. Today, they may also be written in the Berber Latin alphabet or the Arabic script, with Latin being the most pervasive.

The Berber languages have a level of variety similar to the Romance languages, although they are sometimes referred to as a single collective language, often as "Berber", "Tamazight", or "Amazigh". The languages, with a few exceptions, form a dialect continuum. There is a debate as to how to best sub-categorize languages within the Berber branch. Berber languages typically follow verb–subject–object word order. Their phonological inventories are diverse.

Millions of people in Morocco and Algeria natively speak a Berber language, as do smaller populations of Libya, Tunisia, northern Mali, western and northern Niger, northern Burkina Faso and Mauritania and the Siwa Oasis of Egypt. There are also probably a few million speakers of Berber languages in Western Europe. Tashlhiyt, Kabyle, Central Atlas Tamazight, Tarifit, and Shawiya are some of the most commonly spoken Berber languages. Exact numbers are impossible to ascertain as there are few modern North African censuses that include questions on language use, and what censuses do exist have known flaws.

Following independence in the 20th century, the Berber languages have been suppressed and suffered from low prestige in North Africa. Recognition of the Berber languages has been growing in the 21st century, with Morocco and Algeria adding Tamazight as an official language to their constitutions in 2011 and 2016 respectively.

Most Berber languages have a high percentage of borrowing and influence from the Arabic language, as well as from other languages. For example, Arabic loanwords represent 35% to 46% of the total vocabulary of the Kabyle language and represent 44.9% of the total vocabulary of Tarifit. Almost all Berber languages took from Arabic the pharyngeal fricatives /ʕ/ and /ħ/, the (nongeminated) uvular stop /q/, and the voiceless pharyngealized consonant /ṣ/. Unlike the Chadic, Cushitic, and Omotic languages of the Afro-Asiatic phylum, Berber languages are not tonal languages.

"Tamazight" and "Berber languages" are often used interchangeably. However, "Tamazight" is sometimes used to refer to a specific subset of Berber languages, such as Central Tashlhiyt. "Tamazight" can also be used to refer to Standard Moroccan Tamazight or Standard Algerian Tamazight, as in the Moroccan and Algerian constitutions respectively. In Morocco, besides referring to all Berber languages or to Standard Moroccan Tamazight, "Tamazight" is often used in contrast to Tashelhit and Tarifit to refer to Central Atlas Tamazight.

The use of Berber has been the subject of debate due to its historical background as an exonym and present equivalence with the Arabic word for "barbarian." One group, the Linguasphere Observatory, has attempted to introduce the neologism "Tamazic languages" to refer to the Berber languages. Amazigh people typically use "Tamazight" when speaking English. Historically, some Berber groups have used this endonym since Antiquity (such as the Mazices) or continue to do so, although others had their own terms to refer to themselves. For example, the Kabyles use the term "Leqbayel" to refer to their own people, while the Chaouis identified themselves as "Ishawiyen".

Since modern Berber languages are relatively homogeneous, the date of the Proto-Berber language from which the modern group is derived was probably comparatively recent, comparable to the age of the Germanic or Romance subfamilies of the Indo-European family. In contrast, the split of the group from the other Afroasiatic sub-phyla is much earlier, and is therefore sometimes associated with the local Mesolithic Capsian culture. A number of extinct populations are believed to have spoken Afroasiatic languages of the Berber branch. The earliest example of a text possibly written in Berber or Proto-Berber is a single Egyptian papyrus written in the extinct Kehek language originating in the New Kingdom era of Egypt. According to Peter Behrens and Marianne Bechaus-Gerst, linguistic evidence suggests that the peoples of the C-Group culture in present-day southern Egypt and northern Sudan spoke Berber languages. The Nilo-Saharan Nobiin language today contains a number of key loanwords related to pastoralism that are of Berber origin, including the terms for sheep and water/Nile. This in turn suggests that the C-Group population—which, along with the Kerma culture, inhabited the Nile valley immediately before the arrival of the first Nubian speakers—spoke Afroasiatic languages.
