## Abstract

Syringa meyeri C. K. Schneid. 1912 (Oleaceae) is a common dwarf ornamental lilac, native to Northeast China. In this study, the complete chloroplast genome of S. meyeri was assembled, exhibiting a typical quadripartite structure with a total length of 160,459 bp and a GC content of 37.9%. A total of 141 genes were annotated, including 96 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis of 19 cp genomes indicated that S. meyeri is most closely related to S. pubescens subsp. microphylla. These results provide essential genomic resources for future phylogenetic and evolutionary studies in Syringa.
