The complete chloroplast genome of Iris sanguinea was sequenced newly in this study. The total chloroplast genome size of I. sanguinea was 152 408 bp, its structure and gene contents were well conserved as typical chloroplast characteristics. Large single copy (LSC) and small single copy (SSC) of 82 340 bp and 18 016 bp, respectively, were separated from a pair of inverted repeats (IRA and IRB) of 26 026 bp. A total of 112 genes, i.e. 78 protein-coding genes, 30 tRNA genes, and four rRNA genes, were encoded in the chloroplast genome of I. sanguinea. Overall GC content of I. sanguinea was 36.83%. Phylogenetic analysis with the reported chloroplast genomes revealed that I. sanguinea is most closely related to I. gatesii.
