Prolunadu (prōlunāḍu) was an ancient region located in the Indian state of Andhra Pradesh, corresponding to parts of the present-day Pithapuram, Kakinada, and Peddapuram taluks within the Kakinada district.
[1][2][3] It was situated south of Pithapuram and north of the lower Godavari River, encompassing areas to the east of the Eleru River, a tributary of the Godavari.
Prolunadu served as an administrative division of the Eastern Chalukyan kingdom and was established by Vishnuvardhana III in 742 CE.
[6] It was one of the historical regions of Andhra, alongside other divisions such as Pakanadu, Palnadu, Kammanadu, and Renadu.
[1] Prolunadu is mentioned as a vishaya (administrative division) in medieval inscriptions, often noted in records of land grants and other royal decrees.
