The Talodi–Heiban languages are a proposed branch of the hypothetical Niger–Congo family, spoken in the Nuba Mountains of Sudan. The Talodi and Heiban languages are thought to be distantly related by Dimmendaal,^[1] though Glottolog 4.4 does not accept the unity of Talodi–Heiban pending further evidence.^[2]

Roger Blench (2016) notes that the Talodi and Heiban branches share many typological similarities, but few lexical similarities. Blench (2016) considers Talodi and Heiban to each be separate, independent Niger-Congo branches that had later converged due to mutual contact.

Talodi and Heiban had each constituted a group of the Kordofanian branch of Niger–Congo that was posited by Joseph Greenberg (1963); Talodi has also been called Talodi–Masakin, and Heiban has also been called Koalib or Koalib–Moro. Roger Blench notes that the Talodi and Heiban families have the noun-class systems characteristic of the Atlantic–Congo core of Niger–Congo, but that the Katla languages (another putative branch of Kordofanian) have no trace of ever having had such a system, whereas the Kadu languages and some of the Rashad languages appear to have acquired noun classes as part of a Sprachbund, rather than having inherited them. He concludes that the Kordofanian languages do not form a genealogical group, but that Talodi–Heiban is core Niger–Congo, whereas Katla and Rashad form a peripheral branch (or perhaps branches) along the lines of Mande. The Kadu languages may be Nilo-Saharan.

Lafofa (Tegem), sometimes classified as a divergent Talodi language, has a different set of cognates with other Niger–Congo and has been placed in its own branch of Niger–Congo.
