Harit Pradesh (Hindi: हरित प्रदेश, Urdu: ہرِت پردیش) is a proposed new state of India comprising the western parts of Uttar Pradesh state.Braj Pradesh (ब्रज प्रदेश) and Pashchim Pradesh (पश्चिम प्रदेश) are alternative names that have been proposed, because the region incorporates the historic region of Braj and is the western (pashchim in Hindi) part of Uttar Pradesh respectively. Braj Pradesh, however, is a term that has historically been used for parts of the proposed state's territory as well as some adjoining regions of Rajasthan state. Usage of that term by authors or politicians doesn't necessarily denote support for the movement to create a separate state.

Uttar Pradesh is a large state, and "the cultural divide between the east and the west is considerable, with the purabiyas (easterners) often being clubbed with Biharis in the perception of the westerners." At the village level, some commentators have observed that Western Uttar Pradesh resembles Haryana and Rajasthan more than it does Eastern Uttar Pradesh, and the eastern region resembles Bihar more than it does Western Uttar Pradesh. Also, due to the successes of the Green Revolution, Western Uttar Pradesh has experienced both economic and social development, in a fashion similar to Haryana and Punjab. Eastern Uttar Pradesh, like Bihar, has not benefited to the same extent. The resulting disparity is believed to be partially responsible for the demand for separate statehood in Western Uttar Pradesh.
