Mahi Kantha was a political agency or collection of princely states in British India, within the Gujarat Division of Bombay Presidency.

In 1811, when the Maratha power was declining, the British Government stipulated to collect and pay over to the ruler of Baroda the yearly tribute of the Mahi Kantha states.

In 1820 they finally took over the management of the whole territory, agreeing to collect and pay over the tribute free of expense to Baroda, while Baroda was pledged not to send troops into the country, or in any way to interfere with the administration.

After a few disturbances in the 1830s, in 1857-58 and 1867, peace remained unbroken in the region until 1881, when the Bhils of Pol rose against their chief and extorted from him a settlement of their claims.

The states were classified in the following manner: The agency included as well a large number of estates belonging to Rajput or [chuvad 16.gam s.stet Thakur Sahab i people|Thakur saheb]] formerly feudatories of Baroda; several of the states paid tribute to Baroda, and some, being classed as non-jurisdictional thalukdars, were under British administration.
