கௌதமிபுத்ர சதகர்ணி (கி.பி. 78-102) சதவாகனர் ராஜவம்சத்தில் 23ஆம் அரசராக திகழ்ந்தார். சதவாகனர்களில் மிகப்பெரும் மன்னராக இருந்த கௌதமிபுத்ரன் தன் தந்தை சதகர்ணிக்கு பின் அரசன் ஆனார்.
சதகர்ணி தம் ராஜ்யத்தை பெரிதளவில் விரிவடைய வைத்து இரு அஸ்வமேத யாகங்களை நடத்தியவர். When Gautamiputra ascended the throne, the Satavahana Empire was loosely attached and was facing the threats of invasions from Sakas and Yavanas. Gautamiputra defeated the Yavanas, Sakas, and Pahlavas and re-established the ancient glory of the Satavahanas. He overthrew Nahapana and restruck a large number of Ksaharata coins of the Jogalthembi hoard.
The Nasik Prasasti describes Gautamiputra as the ruler of the Aparanta, Anupa, Saurashtra, Kukura, Akara, and Avanti, and he must have wrested them from Nahapana. He also seems to have recovered the territories in Central Deccan, which had been lost by the Satavahanas during the earlier rule of his predecessors. Under him, the Satavahana arms must have reached as far south as Kanchi. He is also credited with the conquest of territories in the Kolhapur area in the Southern Maharashtra, which he seized from the Ananda rulers. Gautamiputra also annexed the Banavasi area, thus established his sway over portions of Karnataka. He was succeeded by his son, Vasisthiputra Sri Pulamavi in about 130 AD.
Gautamiputra Satakarni also defeated the Saka king[மேற்கோள் தேவை] Vikramaditya, thus starting the Shalivahana era or Shaka Calendar which is still used by Gujaratis, Maharashtrians, Telugus, and Kannadigas[மேற்கோள் தேவை].
Gautamiputra Satakarni took the titles of
- Trisamudrapittoyvahana (one whose horses had drunk waters from 3 oceans)
- sakayavanpallavanidusana (destroyer of saka, yavana and pallavas)
