Pseudostellaria okamotoi Ohwi is the endemic species with limited habitat which is subalpine area in central Southern part of the Korean peninsula. In this study, we presented the complete chloroplast genome of P. okamotoi of which length is 149,653 bp. It consists of four subregions: 81,291 bp of large single copy (LSC) and 16,958 bp of small single copy (SSC) regions are separated by 25,702 bp of inverted repeat (IR) regions. It includes 126 genes (81 protein-coding genes, eight rRNAs, and 37 tRNAs). The overall GC content of the chloroplast genome is 36.5\% and those in the LSC, SSC, and IR regions are 34.3\%, 29.3\%, and 42.4\%, respectively.
