A country in Central India. Rujā was once born as an ox there (J.vi.238). It was apparently a centre of the art of sword-making (J.iii.338). Erakaccha, a city in Dasaṇṇa, was the residence of the millionaire (seṭṭhi) Dhanapāla (Pv.ii.7).

The kings of Dasaṇṇa are called Dasaṇṇā. Dasaṇṇa is mentioned in the Mahāvastu (i.34) as one of the sixteen great nations (mahājanapadā), and also in the Mahābhārata (ii.5-10) and the Meghadūta (24-5). It is generally identified with Vidisā or the Bhilsa region in the Central Provinces.
