Agguka I (r. c. 770 – c. 790) was a ruler of the Saindhava dynasty^[2] and the commander of the Saindhava naval fleet during the last quarter of 8th century. He was the son of Krishnaraj.

During his reign the Arabs made a fresh bid to establish their supremacy over Saurashtra. In 756, the Arab governor of Sindh sent a naval fleet against the Saindhavas. This naval attack was repulsed by the Saindhavas as they had a strong naval forces. Later in 776, another naval expedition by the Arabs was defeated by the Saindhava naval fleet under the command of Agguka I. A Saindhava inscription relates that Agguka I inflicted a disastrous defeat on the Arab naval fleets which forced the Arabs to withdraw. After this the Caliph Al-Mahdi gave up the project of conquering any part of India through the Navy. In the Saindhava inscription he was titled as Samudradhipati or Master of the western sea.^[3][4]
