The Dassaretii (Ancient Greek: Δασσαρῆται, Δασσαρήτιοι, Dassaretai, Dassaretioi; Latin: Dassaretae, Dassaretii) were an Illyrian people that lived in the inlands of southern Illyria, between present-day south-eastern Albania and south-western North Macedonia. Their territory included the entire region between the rivers Asamus and Eordaicus (whose union forms the Apsus), the plateau of Korça locked by the fortress of Pelion and, towards the north it extended to Lake Lychnidus up to the Black Drin. They were directly in contact with the regions of Orestis and Lynkestis of Upper Macedonia. Their chief city was Lychnidos, located on the edge of the lake of the same name. One of the most important settlements in their territory was established at Selcë e Poshtme near the western shore of Lake Lychnidus, where the Illyrian Royal Tombs were built.
The Dassaretii were one of the most prominent peoples of southern Illyria, forming an ethnic state. They made up the ancient Illyrian kingdom that was established in this region. The weakening of the kingdom of the Enchelei presumably led to Enchelei's assimilation and inclusion into a newly established Illyrian realm at the latest in the 6th–5th centuries BC, marking the arising of the Dassaretii, who appear to have replaced the Enchelei in the lakeland area.
