Rishyashringa (Sanskrit: ऋष्यशृंग; IAST: Ṛṣyaśṛṅga; Pali: Isisiṅga) is a Rishi mentioned in Indian (Hindu and Buddhist) scriptures from the late first millennium BCE. According to the Hindu epic Ramayana, he was a boy born with the horns of a deer who became a seer and was seduced by royal courtesans, which led to the yajna (fire sacrifice) of King Dasharatha. He also occurs in the Buddhist Jatakas, where he is mentioned as the son of Bodhisatta and was tried to seduce by a royal or divine courtesans.
