The Kwa languages, often specified as New Kwa, are a proposed but as-yet-undemonstrated family of languages spoken in the south-eastern part of Ivory Coast, across southern Ghana, and in central Togo. The Kwa family belongs to the Niger-Congo phylum. The name was introduced in 1895 by Gottlob Krause and derives from the word for 'people' (Kwa) in many of these languages, as illustrated by Akan names. This branch consists of around 50 different languages spoken by about 25 million people. Some of the largest Kwa languages are Akan and Baule.

The various clusters of languages included in Kwa are at best distantly related, and it has not been demonstrated that they are closer to each other than to neighbouring Niger–Congo languages.

Stewart distinguished the following major branches, which historical-comparative analysis supports as valid groups:

The Lagoon languages of southern Ivory Coast are not particularly close to any of these, nor to each other, so they are left ungrouped:

An Esuma language, extinct ca. 1800, remains unclassified.

Since Stewart, Ega has been tentatively removed, the Gbe languages reassigned to Volta–Niger, and Apro added. Some of the Na-Togo and Ka-Togo languages have been placed into separate branches of Kwa. See the infobox at right for the resulting branches.

Ethnologue divides the Kwa languages into two broad geographical groupings: Nyo and Left bank, but this is not a genealogical classification. The Nyo group collapses Stewart's Potou–Tano and Ga–Dangme branches and also includes the ungrouped languages of southern Ivory Coast, while the Ka/Na-Togo and Gbe languages are called Left bank because they are spoken to the east of the Volta River.
