Luri (Northern Luri: لری, Southern Luri: لری) is a Southwestern Iranian language continuum spoken by the Lurs, an Iranian people native to West Asia. The Luri dialects are descended from Middle Persian and are Central Luri, Bakhtiari, and Southern Luri. This language is spoken mainly by the Bakhtiari and the Northern and Southern Lurs (Lorestan, Ilam, Kohgiluyeh and Boyer-Ahmad, Mamasani, Sepidan, Bandar Ganaveh, Bandar Deylam) in Iran.

The Encyclopedia of Islam calls Luri “an aberrant form of archaic Persian.” The language descends from either Middle Persian or Old Persian. It belongs to the “Perside southern Zagros group” (as opposed to Kurdish dialects of northern Zagros), and is lexically similar to modern Persian, differing mainly in phonology.

According to the Encyclopædia Iranica, "All Lori dialects closely resemble standard Persian and probably developed from a stage of Persian similar to that represented in Early New Persian texts written in Perso-Arabic script. The sole typical Lori feature not known in early New Persian or derivable from it is the inchoative marker (see below), though even this is found in Judeo-Persian texts". The Bakhtiāri dialect may be closer to Persian. There are two distinct languages, Greater Luri (Lor-e bozorg), a.k.a. Southern Luri (including Bakhtiari dialect), and Lesser Luri (Lor-e kuček), a.k.a. Northern Luri.

Anonby stated that Luri was a Southwestern Iranian language continuum consisting of the Luristani, Bakhtiari, and Southern Luri languages, and itself was a language continuum between Kurdish and Persian.
