In Greek mythology, Almus (Ἄλμος) was a son of Sisyphus and brother of Glaucus, Ornytion and Thersander. Most of the available information concerning him is recorded in Pausanias' Description of Greece. According to said author, Almus received a small tract of land in Orchomenus from King Eteocles and dwelt there; a village was believed to have been named Almones (later Olmones) after him. This is also mentioned by Stephanus of Byzantium, who refers to Pausanias' work but calls the character Olmus (Ὄλμος) to account for the most recent form of the village's name.
