Vasumitra (or Sumitra, according to the d manuscript of the Matsya Purana) (born ???, reigned 131–124 BCE, died 124 BCE), was the fourth King of the Sunga Dynasty of Northern India. He was the son of Agnimitra by his queen Dharini, and a brother or half-brother of Vasujyeshtha.
In the Malavikagnimitram (Act V, Verse 14), Kalidasa tells us that Vasumitra guarded the sacrificial horse let loose by his grandfather Pushyamitra, and he defeated the armies of the "Yavana" (or Indo-Greeks) on the banks of the Sindhu River.
Bana's Harshacharita mentioned him as Sumitra and informed us that he was killed by Mitradeva (or Muladeva, according to some manuscripts) while enjoying a drama. He was succeeded by Andhraka, Antaka, Bhadraka or Bhadra according to different Puranas.
