Ewe (Eʋe or Eʋegbe [ɛβɛɡ͡bɛ]) is a language spoken by approximately 5 million people in West Africa, mainly in Ghana and Togo. Ewe is part of a group of related languages commonly called the Gbe languages. The other major Gbe language is Fon, which is mainly spoken in Benin. Like many African languages, Ewe is tonal as well as a possible member of the Niger-Congo family.

The German Africanist Diedrich Hermann Westermann published many dictionaries and grammars of Ewe and several other Gbe languages. Other linguists who have worked on Ewe and closely related languages include Gilbert Ansre (tone, syntax), Herbert Stahlke (morphology, tone), Nick Clements (tone, syntax), Roberto Pazzi (anthropology, lexicography), Felix K. Ameka (semantics, cognitive linguistics), Alan Stewart Duthie (semantics, phonetics), Hounkpati B. Capo (phonology, phonetics), Enoch Aboh (syntax), and Chris Collins (syntax).

Some of the commonly named Ewe ('Vhe') dialects are Aŋlɔ, Tɔŋu (Tɔŋgu), Avenor, Agave people, Evedome, Awlan, Gbín, Pekí, Kpándo, Vhlin, Hó, Avɛ́no, Vo, Kpelen, Vɛ́, Danyi, Agu, Fodome, Wancé, Wací, Adángbe (Capo).

Ethnologue 16 considers Waci and Kpesi (Kpessi) to be distinct enough to be considered separate languages. They form a dialect continuum with Ewe and Gen (Mina), which share a mutual intelligibility level of 85%; the Ewe varieties Gbin, Ho, Kpelen, Kpesi, and Vhlin might be considered a third cluster of Western Gbe dialects between Ewe and Gen, but Kpesi is as close or closer to the Waci and Vo dialects, which remain in Ewe in that scenario. Waci intervenes geographically between Ewe proper and Gen; Kpesi forms a Gbe island in the Kabye area.

Ewe is itself a dialect cluster of the Gbe languages, which include Gen, Aja, Kotafon, Mina and Xwla and are spoken from the southern part of Ghana to Togo, Benin and Western Nigeria. All Gbe languages share at least some intelligibility with one another. Some coastal and southern dialects of Ewe include Aŋlɔ, Tongu (Tɔŋu), Avenor, Dzodze, and Watsyi. Some inland dialects indigenously characterized as Ewedomegbe include: Ho, Kpedze, Hohoe, Peki, Kpando, Aveme, Liati, Fódome, Danyi, and Kpele. Though there are many classifications, distinct variations exist between towns that are just miles away from one another.^{[citation needed]}

H is a voiced fricative, which has also been described as uvular, [ʁ], pharyngeal, [ʕ], or glottal [ɦ].

/n/ is typically alveolar as [n̺], but can also be dental as [n̪].

The nasal consonants [m, n, ɲ, ŋ] are not distinctive since they appear before only nasal vowels; therefore, Ewe is sometimes said to have no nasal consonants. However, it is more economical to argue that nasal /m, n, ɲ, ŋ/ are the underlying form and so are denasalized before oral vowels.
