Basseri dialect (Persian: گویش باصری) is a Persian dialect spoken in Fars province by the Basseri people.

[1] It is part of the Southwestern Iranian branch of the Indo-Iranian group of Indo-European languages.

[2][3] Basseri dialect consists of many exclusive Persian words with Old and Middle Persian roots and less Arabic Loanwords, which is a consequence of living in the mountains, nomadism and less connection with urban Persians.

[5] Basseri Persian has 21 consonants, in contrast with Iranian Persian with 23 consonants.

Counties like Abadeh, Eqlid, Pasargad, Jahrom, Marvdasht, Shiraz, Khorrambid, Larestan, and Sarvestan are among the traditional living range of the Basseri.
