Ad Quintum was an ancient settlement and a Roman thermal complex in Illyricum, near Bradashesh, present-day Albania. Ad Quintum was a mutatio of the Via Egnatia, which connected western Illyria with eastern Thrace, from the two starting points of Dyrrhachium and Apollonia, to Byzantium. The two branches of the first part of the Via Egnatia converged at Ad Quintum, then the road continued eastwards through the valley of the Shkumbin.
