<i>Thalictrum elegans</i> Wall. ex Royle, a species within the family Ranunculaceae, is mainly distributed along forest margins and grassy slopes at altitudes 2700-4000 m on the Qinghai-Tibetan Plateau. Despite its wide distribution in alpine ecosystems, its genetic diversity remains poorly understood. In this study, we assembled and characterized the complete chloroplast genome of <i>T. elegans</i>, addressing a significant gap in our understanding of its genetic composition. The chloroplast genome is 155,864 base pairs long and contains 131 genes, including 86 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis of 15 representative <i>Thalictrum</i> species revealed that the genus can be classified into three clades. <i>T. elegans</i> along with another nine other species formed the largest monophyletic clade and is most closely related to <i>T. petaloideum</i> and <i>T. foliosum</i>. These findings enhance our understanding of the genetic diversity of <i>T. elegans</i> and contribute to its conservation and utilization.
