The complete chloroplast genome sequence of Parashorea chinensis, an endangered large tree species in the northern edge of tropical Asia, is determined in this study. The total genome size is 152,002 bp, containing a large single copy (LSC) region (84,094 bp) and a small single copy region (20,003), which were separated by two inverted repeat (IRs) regions (23,954 bp). The overall GC contents of the plastid genome were 37.1%. In total, 116 unique genes were annotated and they consisted of 81 protein-coding genes, 31 tRNA genes, and four rRNA genes. Phylogenetic analysis based on 20 chloroplast genomes indicates that P. chinensis is closely related to P. macrophylla.
