ABSTRACT=<p>In Rosaceae, the replacement of the traditional four-subfamily division (Amygdaloideae or Prunoideae, Maloideae, Rosoideae, and Spiraeoideae) by the three-subfamily division (Dryadoideae, Rosoideae, and Amygdaloideae), the circumscription, systematic position, and phylogeny of genera in Maleae need to be reconsidered. The study aimed to circumscribe Maleae, pinpoint its systematic position, and evaluate the status of all generally accepted genera in the tribe using complete chloroplast genome data. Results indicated that Maleae consisted of pome-bearing genera that belonged to Maloideae as well as four genera (<italic>Gillenia</italic>, <italic>Kageneckia</italic>, <italic>Lindleya</italic>, and <italic>Vauquelinia</italic>) that were formerly considered to be outside Maloideae. The tribe could be subdivided into four subtribes: Gilleniinae (<italic>Gillenia</italic>), Lindleyinae (<italic>Kageneckia</italic> and <italic>Lindleya</italic>), Vaugueliniinae (<italic>Vauquelinia</italic>), and Malinae (all other genera; the core Maleae). Among the 36 recognized genera, <italic>Aria</italic>, <italic>Docyniopsis</italic>, <italic>Chamaemespilus</italic>, and <italic>Mespilus</italic> were not considered distinct and more research is needed to determine the taxonomic status of <italic>Rhaphiolepis</italic> from <italic>Eriobotrya</italic>. Within the core Maleae, five groups were revealed, whereas <italic>Sorbus</italic> L. was split as its members belonged to different groups.</p>
