Triteuta (Ancient Greek: Τριτεύτα; fl. 230–219 BC) was an Illyrian queen and the first wife of the Illyrian king Agron of the Ardiaei (r. 250–231 BC), with whom she had a son named Pinnes.^[1][2]

Sometime before his death (231/230 BC), Agron divorced Triteuta and married Teuta. Their son, crown prince Pinnes, was placed under the guardianship of step-mother Teuta (the Queen regent) until after the First Illyrian War (228 BC).^[3][2] It is believed that, at some point, Teuta abdicated, died, or was removed, and the regency for Pinnes was taken by Demetrius of Pharos.^[4][5]

According to Dio Chrysostom, Demetrius of Pharos married Triteuta and became regent for Pinnes,^{[6] [2]}after the war, thus becoming the most powerful of the Illyrian rulers in the 220s BC.^[7][5]
