The first complete chloroplast genome of Costus viridis (Costaceae) was reported in the current study. The C. viridis genome was 168,966 bp in length and comprised a pair of inverted repeat (IR) regions of 29,166 bp each, a large single-copy (LSC) region of 92,189 bp, and a small single-copy (SSC) region of 18,445 bp. It encoded 133 genes, including 87 protein-coding genes (79 PCG species), 38 tRNA genes (28 tRNA species), and eight rRNA genes (four rRNA species). The overall AT content was 63.75%. Phylogenetic analysis showed that C. viridis was closely related to species Costus osae within the genus Costus in family Costaceae.
