Chimonobambusa hirtinoda, a threatened species, is only naturally distributed in Doupeng Mountain, Duyun, Guizhou, China. Next-generation sequencing (NGS) is used to obtain the complete chloroplast (cp) genome sequence of C. hirtinoda. The sequence was assembled and analyzed for phylogenetic and evolutionary studies. Additionally, we compared the cp genome of C. hirtinoda with previously published Chimonobambusa species. The cp genome of C. hirtinoda has a total length of 139, 561 bp and 38.90% GC content. This genome included a large single -copy (LSC) region of 83, 166 bp, a small single-copy (SSC) region of 20, 811 bp and a pair of inverted repeats of 21,792 bp each. We discovered 130 genes in the cp genome, including 85 protein-coding genes, 37 tRNA, and 8 rRNA genes. A total of 48 simple sequence repeats (SSRs) were detected. The A/U preference of the third nucleotide in the cp genome of C. hirtinoda was obtained by measuring the codon usage frequency of amino acids. Furthermore, phylogenetic analysis using complete cp sequences and matK gene revealed a genetic relationship within the Chimonobambusa genus. This study reported the chloroplast genome of the C. hirtinoda.
