Opisthopappus taihangensis (Ling) Shih is a monotypic species (Anthemideae, Asteraceae) and an endemic endangered plant of China. In this study, we sequenced the complete chloroplast genome of O. taihangensis using Illumina HiSeq X Ten platform. The total length of O. taihangensis chloroplast genome is 151,089 bp, including a large single-copy region of length 82,877 bp, a small single-copy region of length 18304 bp, and a pair of 24,954-bp inverted repeat regions. The chloroplast genome of O. taihangensis has 132 genes, including 87 protein-coding, eight ribosomal RNA, and 37 transfer RNA genes. The overall GC content of the whole genome was 37.5%. The phylogenetic analysis revealed a close relationship between O. taihangensis and Chrysanthemum boreale.
