<i>Forsythia saxatilis</i> (Nakai) Nakai is an endemic species in Korea. We present the second complete chloroplast genome sequence of <i>F. saxatilis</i> showing that the chloroplast genome is 156,376 bp in length containing four subregions: a large single-copy (LSC) region of 87,097 bp, a small single-copy (SSC) region of 17,859 bp, and a pair of inverted repeat regions (IRs) of 25,710 bp. The genome contains 131 genes including 88 protein-coding genes, 35 <i>tRNA</i>s, and eight rRNAs. We found 40 base differences in 17 sites between our chloroplast genome and the previously reported chloroplast genome sequences of <i>F. saxatilis</i>. All of the differences were found in a region of 832 bp in the LSC region except for one site, which indicated potential sequencing errors in building the previously reported genome because of little substitutions in the homologous region of the other <i>Forsythia</i> species and even of <i>Abeliophyllum distichum</i>, a sister to <i>Forsythia</i>. The new chloroplast genomes of <i>F. saxatilis</i> and those of <i>F. x intermedia</i> and <i>F. viridissima</i> are identical, which suggests that <i>F. saxatilis</i> is maternally closely related to the other two species.
