Indian author and epic poet (epic) whose Naiadhīyacarita, or Naiadha, is among the most popular mahākāvyas in Sanskrit literature.

The details of Śrīharsha's life are uncertain. Reportedly, when Śrīharsha's father, a poet in King Vijayacanra's court in Kannauj, was disgraced in a poetry contest, he retired and asked Śrīharsha to avenge him. In time Vijayacanra became Śrīharsha's patron, and it was at the king's request that the poet composed Naiadhīyacarita. Among his other writings are treatises on elements of Buddhist and Vedanta beliefs and eulogies on late kings. Persecuted by a queen jealous of an honour bestowed upon him, he retired to a quiet life by the Ganges River.

Naiadhīyacarita, in 22 cantos, is a retelling of the tale of Nala, king of Niaha, and amayantī, princess of Viarbha, from the Mahabharata. It is a story of love overcoming obstacles, ending happily in marriage, and the poem is especially notable for its descriptive embellishments and skillful presentation of emotion. Śrīharsha's mastery of metre is evident, but he has been criticized for occasional obscurity and excessive verbal ornamentation.
