A complete, up to date checklist of Alyssum species reported from Iran is presented in this review. The distribution of these species was considered in Iran and in the adjacent countries, too. Additional records were obtained from Flora Iranica, Flora of Turkey and other references. In Iran some species (e. g., Alyssum hezarmasjedensis, A. mozaffarianii, A. persicum, A. polycladum, A. stipitatum, A. turgidum) have very restricted distribution. Iran is the second important locality for the following species: A. anatolicum, A. contemptum, A. filiforme, A. iranicum, A. lycaonicum, A. niveum, A. penjwinense. The other Alyssum species are widespread in Iran and in the adjacent countries.
