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 Côte d'Ivoire, across southern Ghana, and in central Togo. The name was introduced 1885 by Gottlob Krause and derives from the word for 'people' (Kwa) in many of these languages, as illustrated by Akan names.

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 neighboring 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:

Since Stewart, Ega has been tentatively removed, and the Gbe languages reassigned to Volta–Niger. 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.
