Quediina is a mega-diverse subtribe of rove beetles (Staphylinidae: Staphylinini) comprising hundreds of species globally, with exceptional species richness in north and south temperate regions. The subtribe has historically been defined by convention rather than clear synapomorphies, and recent phylogenetic studies have demonstrated polyphyly, leading to major taxonomic revisions. Formerly quediine genera from the Afrotropical region have been reassigned to unrelated lineages within Staphylinini. The subtribe includes economically important genera such as Quedius and Bolitogyrus.
