The complete chloroplast genome of Corydalis inopinata Prain ex Fedde was assembled and characterized in this study. The chloroplast genome was 181,335 bp in length, consisting of a large single-copy (LSC) region of 91,727 bp, a small single-copy (SSC) region of 1502 bp, and a pair of inverted repeat (IR) regions of 44,053 bp. It encoded 110 unique genes, including 68 protein-coding genes, 29 tRNA genes, 4 rRNA genes, and 9 pseudogenes. Phylogenetic analyses by maximum likelihood (ML) and Bayesian inference (BI) revealed that C. inopinata was closely related to C. conspersa Maxim. with full support in the present sampling. The complete plastid genome provided in this work would be useful for elucidating the taxonomy, phylogeny, and evolution of C. inopinata and other related species.
