Vasabha (Sinhala: වසභ) was a monarch of the Anuradhapura period of Sri Lanka. He is considered to be the pioneer of the construction of large-scale irrigation works and underground waterways in Sri Lanka to support paddy cultivation. 11 reservoirs and 12 canals were constructed during his reign. He also constructed several Buddhist temples in addition to renovating already existing ones. Vasabha started a new dynasty in the history of Sri Lankan monarchs, having seized the throne after killing Subharaja, the then ruler of Anuradhapura.
