Monunius (Ancient Greek: Μονούνιος; ruled c. 290 – c. 270 BC) was an Illyrian king of Dardania. As a figure, Monunius has
left more archaeological traces than historical records. Monunius was a strong opponent of Macedonia but offered aid of 10,000
soldiers to Ptolemy Keraunos during the Gallic Invasions, which was refused. The Dardanian State while headed by Monunius
ranked among the strongest in the Balkans at that time. The invasions of the Gauls through the Balkans did not affect the
Dardanians as much as the Macedonians.
