Jamadagni is a sage in Hindu literature. He is regarded in Hindu tradition to be one of the Saptarishi in the 7th, and the current age of Manvantara.
Parashurama avenges his dead father Jamadagni.
The Saptarshi are the seven seers of ancient India who are extolled in the Vedas, and other Hindu literature such as the Skanda Purana. The Vedic Samhitas never enumerate these rishis by name, although later Vedic texts such as the Brahmanas and Upanisads do so.
