A revision of the genus Dianthus L. in Iran, including notes on the taxonomic problems, used characters, identification key, litera­ture, synonyms, descriptions, type localities, geographical dis­tributions, specimens seen and finally additional notes, is presented. Altogether ۳۴ species are recognized from Iran. ۵ new species, D. denaicus, D. diversifolius, D. hafezii, D. rudbaricus and D. sahandicus, are described. A new species is recognized but, due to the poor material, no name and no Latin description are given for it. The following names are for the first time treated as syn­onyms: D. fallax  Rech. f. & Esfandiari (= D. orientalis Adams), D. binaludensis Rech. f. (= D. polyepis Bienert ex Boiss.), D. stapfii Lemperg (= D. macranthus Boiss.), D. mazanderanicus Rech. f. (= D. tabrisianus Bienert ex Boiss.), D. paniculatus Pau (= D. strictus Banks & Sol.) and D. coloratus (Bornm.) Hand. - Mzt. (= D. pachypetalus Stapf). ۴ species, D. armeria, D. basianicus, D. calocephalus and D. inamoenus are new records to the flora of Iran.
