: Echinococcus granulosus causes cystic echinococcosis in intermediate hosts, such as sheep, cattle, goats, camels, and horses. Cystic echinococcosis is an essential parasitic disease that affects humans and animals and constitutes a significant public health and economic problem worldwide. This study aimed to determine the molec-ular characterization and phylogenetic analysis of Echinococcus granulosus in sheep???s livers and lungs. The genetic variation was performed by directly sequencing the mitochondrial DNA (mtDNA) genes coding of the NADH dehy-drogenase subunit 1 (ND1). The evidence from molecular studies and DNA sequencing revealed that the isolates of Echinococcus granulosus in Kirkuk city are related to the sheep strain G1 genotype. The alignment analysis showed that there is a concordance between isolates with each other by 99%. When comparing the results with Genbank, it indicated the occurrence of genetic variations between nucleotides represented by eleven codons, seven of which rep-resented transversion mutations, and four were transition mutations.
