Rewa Kantha was a political agency of British India, managing the relations (indirect rule) of the British government's Bombay Presidency with a collection of princely states.

The native states came under British subsidiary alliances after the Third Anglo-Maratha War of the early 19th century.

[3] The total surface was 4,971.75 square miles, comprising 3,412 villages, with a population of 479,055, yielding 2,072,026 Rupees state revenue and paying 147,826 Rupees tribute (mostly to the Gaikwar Baroda State).

Bombay state was split along linguistic lines in 1960, and Rewa Kantha became part of Gujarat, like Saurashtra State.

The total area of the states the agency related to was 12,877 km2 (4,972 sq mi).
