Megachilini is a tribe of leaf-cutter and resin bees.
The Megachilini is the most speciose tribe within Megachilidae, comprising four genera: Coelioxys Latreille, Megachile Latreille, Noteriades Cockerell and Radoszkowskiana Popov. In spite of its high diversity and ubiquity, the phylogenetic relationships both within and among the genera are still obscure.
