Salix wilhelmsiana M.B. Bieberstein 1819 is a perennial woody plant with high economic and ecological value. In this study, we annotated the chloroplast (cp) genome of Salix wilhelmsiana M.B. The results showed that the length of the complete cp genome is 155,577 bp, which is typically composed of two single-copy regions (large single-copy (LSC) of 84,439 bp and small single-copy (SSC) of 16,221 bp) and a pair of IR regions of 27,457 bp with a quadripartite structure. The genome contains 129 genes, including 84 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The GC content was 36.70%. Phylogenetic analysis based on cp genome sequences of 19 species from the Salicaceae family revealed that S. wilhelmsiana M.B. is closely related to S. viminalis var. gmelinii.
