Sweet marjoram (Origanum majorana) is an aromatic herb in the Lamiaceae family. This study aims to report the complete chloroplast nucleotide sequence of marjoram and the phylogenetic relationship with other Lamiaceae species. The total length of this plastome is 151,841 bp, containing a pair of inverted repeat regions (25,558 bp), separated by a large single copy region (83,035 bp) and a small single copy (17,690 bp). The genome encodes 132 genes, including 86 protein-coding genes, 36 tRNA genes, and eight rRNA genes. Phylogenetic tree analysis indicated that O. majorana is the most closely related to Origanum vulgare.
