Genetic diversity and population structure of Holothuria leucospilota in the north of Persian Gulf and Oman Sea by using DNA sequencing method was investigated. For this purpose, samples were captured from Bushehr, Bandar abbas and Chabahar. DNA from fin samples was extracted using Ammonium Acetate method. Polymerase Chain Reaction (PCR) was conducted on the targeted DNAs and DNA sequencing was carried out. The mean of haplotype diversity was high , Chabahar, Bandar abbas and Bushehr. The lowest genetic differences were observed between Bandar abbas and Bushehr and the highest between Chabahar and Bushehr. The highest genetic distance was observed between Chabahar and Bushehrand the lowest betwee Chabahar and Bushehr . The neutrality test of Tajima,s D and Fu, s Fs revealed non-significant negative value for these populations. Subjected to phylogenetic tree construction including neighbor-joining and Unweighted Pair Group Method all Holothuria leucospilata haplotypes in one group. Result showed different population of Holothuria leucospilota which should be considered in management of this economically important species.
