The Datta dynasty is a dynasty of rulers who flourished in the northern India in the areas of Mathura and Ayodhya around the 1st century BCE – 1st century CE.

The known Datta rulers are:[2] The coins of Ramadatta usually represent a Lakshmi standing, and facing elephants.

[2] In the archaeological excavations of Sonkh, near Mathura, the earliest coins of the Northern Satraps level were those of Hagamasha and Ramadatta.

Since the Indo-Greeks were in control of Mathura around the same time frame (150–50 BCE) according to the Yavanarajya inscription, it is thought that there may have been a sort of tributary relationship between the local Datta or Mitra dynasty and the Indo-Greek kings.

[4] Alternatively, the Datta and Mitra dynasties of rulers may simply have replaced Indo-Greek rule in the region, before the advent of the Indo-Scythian Northern Satraps and then the Kushans.
