Abstract True hoppers, consisting of Fulgoromorpha and Cicadomorpha, are plant feeders with very high species-level diversity. A large number of true hopper fossils have been reported from eastern Asia, especially from the Middle to Late Jurassic Yanliao Biota, the Early Cretaceous Jehol Biota and mid-Cretaceous Kachin amber in the last two decades. Herein, true hoppers from the Jurassic and Cretaceous of eastern Asia are reviewed, and combining palaeontological data from other regions of the world and recent advances of molecular studies, the evolutionary history of true hoppers in the mid–late Mesozoic is discussed. Permocicada beipiaoensis Wang, 1987 and Archijassus plurinervis Zhang, 1985 are here excluded from Prosboloidea and Archijassidae, respectively. By the end of 2020, a total of 203 species with definite systematic position had been documented in the Jurassic and Cretaceous of eastern Asia (China, Myanmar, Siberia, Mongolia, Japan and Korea), and were attributed to 116 genera in 22 families and 7 superfamilies. Available fossil data suggest that true hopper components strongly changed in the Cretaceous: primitive groups reduced and went extinct successively, and the origin and/or early diversification of most lineages (family or subfamily level) occurred, likely owing to the displacement of host-plants in the angiosperm floristic revolution.
