In Hindu mythology, Devayani (Sanskrit: देवयानी, Devayānī) was the daughter of Shukracharya and his wife Jayanti, daughter of Indra. In her early life, she was rejected by Kacha, the son of Brihaspati. Thus Devyani cursed him he will never be able to use his knowledge, in turn Kacha also cursed Devayani that she would not get married to any devas.
She later married Yayati, son of Nahusha whom she encountered when the princess Sharmishtha pushed her into a well. Devayani asked Yayati to marry her as he had clasped her hand while lifting her out of the well. Yayati and Devayani had two sons, Yadu and Turvasu. Devayani also means "main goddess" or "mastermind".
