Zannichellia palustris Linnaeus 1753 is a cosmopolitan submerged species capable of rapidly responding to environmental changes, with potential applications in the ecological treatment of heavy metal pollution in water bodies. This study aimed to characterize the complete chloroplast genome of Z. palustris, which has not been reported previously. The chloroplast genome of Z. palustris displays a quadripartite structure with a length of 155,262 base pairs (bp), comprising a large single copy (LSC) region of 85,397 bp, a small single copy (SSC) region of 18,057 bp, and a pair of inverted repeat (IR) regions of 25,904 bp. The GC content of the genome is 35.8%, with corresponding values of 33.4% for the LSC, 28.2% for the SSC, and 42.5% for the IR regions. The genome contained 130 genes, including 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis within the order Alismatales revealed that Z. palustris clusters with the clade of Potamogeton perfoliatus, P. crispus and Stuckenia pectinata.
