The genus <i>Artocarpus</i> J. R. Forst. & G. Forst., with about 70 species worldwide, contains roughly 15 species in China. Nevertheless, the phylogenetic relationships among these Chinese <i>Artocarpus</i> are incompletely understood. Here, we analyzed plastomes of ten Chinese <i>Artocarpus</i> species. These plastomes have a typical quadripartite structure, and sizes ranging from 160,184 bp to 161,009 bp. Simple sequence repeats (SSRs) numbered 73 to 95, while dispersed repeats ranged from 51 to 81. The protein-coding genes displayed comparable RSCU patterns with minor variations. The genes ycf1 and ndhF showed varying degrees of expansion and contraction at their boundaries. Analysis of selective pressures in 72 protein-coding genes revealed a predominance of purifying selection, with an average Ka/Ks ratio of 0.23, as well as evidence of positive selection in specific genes. Positive selection was detected in the genes <i>atp</i>F, <i>rpo</i>C2, <i>rpo</i>C1, <i>cem</i>A, <i>rpl</i>20, <i>clp</i>P, <i>pet</i>D, <i>rps</i>8, <i>rps</i>3, <i>rps</i>19, <i>ycf</i>2, <i>ycf</i>1, and <i>ndh</i>D within the plastomes of ten <i>Artocarpus</i> species in China. Phylogenetic analyses demonstrated a high degree of consistency in their main topological structures, dividing the genus <i>Artocarpus</i> into Clade A and Clade B. The highly variable regions <i>trn</i>H-<i>psb</i>A, <i>trn</i>G-UCC-<i>trn</i>R-UCU, <i>trn</i>S-UGA, <i>trn</i>T-UGU-<i>trn</i>L-UAA, and <i>rps</i>19 were suggested as molecular markers for distinguishing between these clades. Additionally, the study also identified 12 distinct highly variable regions, which represent potential molecular markers for <i>Artocarpus</i>. These results not only enhance our understanding of the phylogenetic relationships within Chinese <i>Artocarpus</i> but also underscore the utility of these specific molecular markers for future studies in this genus.
