Nava-sahasanka-charita (IAST: Nava-sāhasānka-carita, "the biography of the New Sahasanka") is a Sanskrit-language epic poem written by the Paramara court poet Padmagupta, who lived in 10th-11th century. It is fantasy re-telling of the exploits of the Paramara king Sindhuraja, who bore the title Nava-sahasanka, and ruled the Malwa region in central India.
In the epic, Sindhuraja shoots a deer with a golden arrow during a hunting expedition in the Vindhyas. The deer escapes to its owner, the Naga princess Shashiprabha, who sees the hero's title "Nava-Sahasanka" written on the arrow. Meanwhile, in pursuit of the deer, the king comes across a necklace bearing Shashiprabha's name. Sindhuraja and Shashiprabha subsequently meet, and fall in love with each other. Shashiprabha's father has decided to marry her to the man who brings him a golden lotus in the possession of the demon king Vajrankusha. Sindhuraja goes on a campaign against Vajrankusha, guided by the river goddess Narmada and sage Vanku, and supported by the Naga warrior Ratnachuda and the vidyadhara leader Shashikhanda. He defeats the demon king, brings the lotus, and marries Sahshiprabha.
