The aim of this study is to expand the knowledge of the Quedius fauna (Coleoptera: Staphylinidae: Staphylinini: Quediina) on the Macedonian side of Shar Planina. A total of 70 specimens belonging to 12 species are reported. Ten species are recorded from Shar Planina for the first time. Three species,Q. boops (GRAVENHORST, 1802), Q. persimilis Mulsant & Rey, 1876 and Q. fuliginosus Gravenhorst, 1802 are reported from Macedonia for the first time. Omitted data in the latest edition of Catalogue of Palaearctic (Smetana & Schülke, 2015) are noted. A list of all Quedius species recorded from Macedonia and Shar Planina is given. The intraspecific variation of Q. nemoralis Baudi, 1848 and Q. illyricus Wendeler, 1928 is discussed.
