Taiwania cryptomerioides is an endangered relict conifer species native to East Asia with a variety of practical applications. To contribute to its conservation and sustainable utilization, its complete chloroplast genome was assembled from Illumina sequencing reads. The circular genome is 131,427 bp in size with a biased nucleotide composition (33.5% A, 17.5% C, 17.2% G & 31.8% T). It encodes a panel of 114 gene species, including 83 protein-coding genes (PCGs) and 31 tRNAs. Gene duplication was detected for three tRNA gene species (trnI-CAU, trnQ-UUG & trnV-GAC). Besides, 15 gene species (atpF, ndhA, ndhB, petB, petD, rpl16, rpl2, rpoC1, rps16, trnA-UGC, trnG-UCC, trnI-GAU, trnK-UUU, trnL-UAA & trnV-UAC) possess a single intron, and another one (ycf3) has a couple of introns. Phylogenetic analysis suggests that T. cryptomerioides and T. flousiana are closely related to each other within the family Cupressaceae.
