Magnolia sieboldii K. Koch (Magnoliaceae) is a tree species with high landscaping value, whose resource has been declining due to unreasonable exploitation. In this study, we sequenced, assembled and annotated the complete chloroplast (cp) genome of M. sieboldii. The length of M. sieboldii complete cp genome was 160,274 bp, with a typical quadripartite structure comprising a pair of inverted repeat regions (IRs; 26,588 bp), a large single copy region (LSC; 88,267 bp) and a small single copy region (SSC; 18,831 bp). The whole cp genome contained 111 unique genes, including 78 protein-coding genes (PCGs), 29 transfer RNA (tRNA) genes and four ribosomal RNA (rRNA) genes. In addition, 17 genes in IRs were duplicated. The overall CG content was 39.2%. The maximum likelihood (ML) phylogenetic analysis indicated that M. sieboldii was relatively closed to the M. officinalis and M. tripetala. Our research would provide a valuable genetic resource for M. sieboldii.
