Heritiera angustata (Malvaceae) is an evergreen tree distributed in the Chinese provinces of Hainan and Yunnan and in Cambodia. In China, it is listed as 'Endangered' (EN) China Red List of Higher Plants, although it is not protected by law. The complete chloroplast (cp) genome sequence of this threatened species is reported in this study, based on high-throughput sequencing (Illumina). The complete cp genome is 168, 953 bp in length, containing a pair of inverted repeat regions (IRs) of 34,491 bp, a large single copy (LSC) region of 89,054 bp, and a small single copy (SSC) region of 10,917 bp. The cp genome contains 129 genes, consisting of 85 protein-coding genes, 36 tRNA genes and eight rRNA genes. The overall AT content in the cp genome of H. angustata is 63.2%. The phylogenetic analyses indicate that there is a close relationship between H. angustata and Firmiana pulcherrima.
