Tarumanagara or Taruma Kingdom or just Taruma is an early Sundanese Indianized kingdom, whose fifth-century ruler, Purnavarman, produces the earliest known inscriptions on Java island.

The kingdom is not far from modern Jakarta, and according to Tugu inscription Purnavarman apparently built a canal that changed the course of the Cakung River, and drained a coastal area for agriculture and settlement.

In his inscriptions, Purnavarman associated himself with Vishnu, and Brahmins ritually secured the hydraulic project.

Tarumanagara exists between 358–669.

The earliest known written records of Tarumanagara’s existence are inscribed monument stones, called prasasti in the Indonesian language.
