The Betwa (Sanskrit: वेत्रावती) is a river in Central and Northern India, and a tributary of the Yamuna.

The confluence of the Betwa and the Yamuna rivers is in Hamirpur district in Uttar Pradesh where Yamuna flows north and Betwa flows just south of Hamirpur.

In accordance with an inter-state agreement between the states of Uttar Pradesh and Madhya Pradesh in 1973, Betwa River Board (BRB) was constituted under the Betwa River Board Act, 1976.

Latterly the National Board for Wildlife (NBWL) has given its clearance for the Ken-Betwa inter-linking of rivers (ILR) project.

[4] The project to link Ken and Betwa rivers has raised environmental concerns: "Proponents of the project, led by the Union Water Ministry, say that the proposed Daudhan dam and the 2.5 km [1.6 mi] canal — the key structures of the project — that will transfer surplus water from the Uttar Pradesh section of the Ken to the Betwa in Madhya Pradesh are critical to irrigate nearly 700,000 hectares [1,700,000 acres] in drought-ravaged Bundelkhand.
