The complete chloroplast genome of Kolkwitzia amabilis (Caprifoliaceae) is first presented in the current study. The cp genome of K. amabilis was 156 875 bp in length and composed of two short inverted repeat (IRa and IRb) regions of 23 946 bp which were separated by a small single copy (SSC) region of 18 846 bp and a large single copy (LSC) region of 90 137 bp. The genome encoded 130 genes contained 81 coding genes, 39 tRNA genes, and 8 rRNA genes. The overall AT content of K. amabilis is 61.6% and the corresponding values of the SSC, LSC and IR regions are 66.8%, 64.1%, and 57.3%, respectively. The phylogenetic analysis based on the maximum parsimony tree revealed that K. amabilis was closely related to Lonicera japonica.
