Trishanku (Sanskrit: त्रिशङ्कु, romanized: Triśaṅku), born Satyavrata, is a king of the Suryavamsha (Solar dynasty) featured in Hindu texts[which?].

He is described as having greatly assisted the preceptor's traditional rival, Vishvamitra, when the latter's family suffered from hunger, offering them food daily during a severe drought.

When Vasishtha realised what had occurred, he cursed the prince to become a chandala and declared that he would henceforth be called Trishanku (three sins), referring to his actions of provoking the fury of his father, his abduction of another man’s bride, and his consumption of the flesh of a cow.

[4][5] According to the Ramayana, Trishanku is described to be a self-controlled, truthful, and righteous king in the Ikshvaku dynasty who wanted to ascend to Svarga in his own body.

[7] When Trishanku told Vasishtha's sons of his intention to seek some other means to achieve his goal, they angrily cursed him so that he would physically transform into a chandala.

[11] Eventually, an enraged Vishvamitra, threatening to undermine Indra's authority, secures the king a place among new stars, constellation, and even devas he creates through his own ascetic power, albeit with his head downwards.
