The first complete mitochondrial genome of Heteractis doreensis (Quoy & Gaimard, 1833) was sequenced to clarify its mitogenomic features and phylogenetic position. The circular genome is 20,720 bp long with 60.34% A+T content, comprising 13 protein-coding genes, two ribosomal RNA genes, two transfer RNA genes, and one putative open reading frame. Maximum-likelihood phylogenetic analysis of 19 Hexacorallia species revealed that H. doreensis clusters with Stichodactyla haddoni and Heteractis crispa in a strongly supported clade (bootstrap = 96%) within Stichodactylidae. These findings provide valuable molecular insights into the evolution and phylogeography of H. doreensis, supporting future research on its conservation and breeding.
