Quercus tarokoensis is an endemic species to Taiwan, China. The complete plastid genome of Q. tarokoensis was assembled from Illumina pair-end sequence reads. The whole plastome was 161,355 bp in length and presented a quadripartite structure consisting of two copies of inverted repeat (IR) regions (25,860) separated by a large single copy region (90,602 bp) and a small single copy region (19,033 bp). The plastome of Q. tarokoensis encoded a total of 134 genes, including 86 protein-coding genes (79 PCG species), 40 tRNA genes (33 tRNA species), and 8 rRNA genes (4 rRNA species). The overall GC content of Q. tarokoensis plastome is 36.8%. A maximum likelihood phylogenetic analysis based on 33 complete plastomes revealed that Q. tarokoensis was collectively sister to a clade of (Quercus variabilis, (Quercus dolicholepis, Quercus baronii)) with high support.
