Abstract Cyperaceae (sedges) are the third largest monocot family and of considerable economic ecological importance. Sedges represent an ideal model to study evolutionary biology due their species richness, global distribution, large discrepancies in lineage diversity, broad range preferences, adaptations including multiple origins C 4 photosynthesis holocentric chromosomes. Goetghebeur′s seminal work on published 1998 provided most recent complete classification at tribal generic level, based a morphological inflorescence, spikelet, flower, embryo characters, plus anatomical other information. Since then, several family‐level molecular phylogenetic studies using Sanger sequence data have been published. Here, more than 20 years after last comprehensive family, we present first family‐wide phylogenomic targeted sequencing Angiosperms353 probe kit sampling 311 accessions. In addition, 62 accessions available from GenBank were mined for overlapping reads included analyses. Informed by this backbone phylogeny, new tribal, subtribal, levels is proposed. The majority previously recognized suprageneric groups supported, time, establish support tribe Cryptangieae as clade genus Koyamaea . We provide taxonomic treatment identification keys diagnoses 2 subfamilies, 24 tribes, 10 subtribes, basic information 95 genera. includes five subtribes Schoeneae: Anthelepidinae, Caustiinae, Gymnoschoeninae, Lepidospermatinae, Oreobolinae.
