The ****Mordvinic languages, also known as the Mordvin, Mordovian or Mordvinian languages (, mordovskiye yazyki), are a subgroup of the Uralic languages, comprising the closely related Erzya language and Moksha language, both spoken in Mordovia. Previously considered a single "Mordvin language", it is now treated as a small language grouping. Due to differences in phonology, lexicon, and grammar, Erzya and Moksha are not mutually intelligible. The two Mordvinic languages also have separate literary forms. The Erzya literary language was created in 1922 and the Mokshan in 1923. Phonological differences between the two languages include: The medieval Meshcherian language may have been Mordvinic or close to Mordvinic.

Instead, some Uralicists now prefer a rapid expansion model, with Mordvinic as one out of nine primary branches of Uralic; others propose a close relation between Mordvinic with the Finnic and Saamic branches of Uralic.
