Raghuvaṃśa is a Sanskrit epic poem (mahakavya) by the celebrated Sanskrit poet Kalidasa. Though an exact date of composition is unknown, the poet is presumed to have flourished in the 5th century CE. It narrates, in 19 sargas (cantos), the stories related to the Raghu dynasty, namely the family of Dilipa and his descendants up to Agnivarna, who include Raghu, Dasharatha and Rama.

Mahākāvya, also known as sargabandha, is a genre of Indian epic poetry in Classical Sanskrit. The genre is characterised by ornate and elaborate descriptions of scenery, love, battles and so on — in short, everything that tests a poet's skill at description. Typical examples of mahākāvya are the Kumarasambhava and the Kiratarjuniya.
