In this study, the complete chloroplast (cp) genome sequence of Koelreuteria paniculata was determined using next-generation sequencing. The entire cp genome was determined to be 163,258 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 90,236 of 18,268 bp, respectively, which were separated by a pair of 27,377 bp inverted repeat (IR) regions. The genome contained 131 genes, including 85 protein-coding genes, 37 tRNA genes, 8 rRNA genes, and 1 pseudogene. The overall GC content of the K. paniculata cp genome was 37.3%, whereas the corresponding values for the LSC, SSC, and IR regions were 35.3, 31.3, and 42.6%, respectively. The phylogenetic analysis demonstrated a close relationship between K. paniculata and Sapindus mukorossi.
