The North-East Democratic Alliance ( NEDA) is a political coalition that was formed on May 24, 2016, by Bharatiya Janata Party. The motive of the new political front was to protect the interest of the people of the region as well as uniting non-Congress parties in Northeast India.

The alliance was established after Bharatiya Janata Party led National Democratic Alliance which includes parties like Asom Gana Parishad and Bodoland People's Front formed its first government in Assam. The founding political parties of North-East Democratic Alliance led by Bharatiya Janata Party on May 26, 2019, included Naga People's Front, Sikkim Democratic Front, People's Party of Arunachal, Asom Gana Parishad and Bodoland People's Front.
