Gunaga Vijayaditya III (848 – 892 AD) was the most powerful king of the Vengi kingdom.

[2][3] His reign began with an expedition under his talented general Pandaranga to crush the Boya-Kottamas, a sturdy race of warriors who inhabited the northern borders of the Pallava kingdom (present-day Nellore district).

[3][1] Gunaga Vijayaditya III, unlike his predecessors, maintained friendly relations with the Rashtrakuta emperor Amoghavarsha I and was sent to Gangavadi to crush the rebellion of the Western Gangas and other rebellious vassals.

He defeated and pursued Krishna II, the successor of Amoghavarsha, till Chedi in central India.

This caused a big setback for the Chedi king Shankaragana II (890-910 CE).
