Bihar and Orissa was a province of British India which included the present-day Indian states of Bihar, Jharkhand, and a part of Odisha. The territories were conquered by the British in the 18th and 19th centuries, and were part of the Bengal Presidency, the largest British province in India.

On 1 April 1912 both Bihar and Orissa division were separated from the Bengal Presidency as Bihar and Orissa Province. On 1 April 1936 Bihar and Orissa became separate provinces.

In 1756 Bihar was part of Bengal Subah of Mughal Empire while Orissa was a different Subah.

The Treaty of Allahabad was signed on 16 August 1765, between the Mughal Emperor Shah Alam II, son of the late Emperor Alamgir II, and Robert, Lord Clive, of the East India Company, as a result of the Battle of Buxar of 22 October 1764. The Treaty marks the political and constitutional involvement and the beginning of British rule in India. Based on the terms of the agreement, Alam granted the East India Company Diwani rights, or the right to collect taxes on behalf of the Emperor from the eastern province of Bengal-Bihar-Orissa. Bihar and Orissa was separated from Bengal on 1 April 1912, with Patna as capital & Puri as summer capital. A number of princely states, including the Orissa Tributary States, were under the authority of the provincial governor.
