Kaderbad Narasinga Rao, (sometimes spelled as Khaderbad), popularly known as "Nandyal Gandhi" (14 November 1888 – 2 June 1963), was a freedom fighter from Andhra Pradesh who fought for India's independence, philanthropist, social reformer, and political leader who worked tirelessly throughout his life to uplift disadvantaged people and eradicate untouchability.

Narasinga Rao was born in Nandyal in (Madras Presidency of India) on 14 November 1888 to Sri Kaderbad Venkata Subbarao, an attorney and Smt.

Though Narasinga Rao was born into a traditional Brahmin Family, he was deeply influenced by the efforts of Mahatma Gandhi to eradicate untouchability in the society.

Moved by the plight of poor people (called untouchables in those days), he strived throughout his life to integrate them into society and provide them economic opportunities and equal social status.

His stature, wealth, political influence, and social status gradually forced other members of his community and others to follow his reforms.

Using his own resources, he established a "Harijan Boys Hostel" where children of poor people were provided with room to stay, food to eat, and education.

Using his influence and contacts with political leaders and high officials in the administration, he started several programs that helped poor farmers.

He was instrumental in getting a bridge constructed across the Kundu River that helped these farmers more easily reach their lands, even during the rainy season and floods.

He was elected to the Taluka Board and served as the President of Atmakur (in present-day Kurnool District of Andhra Pradesh) and later Nandyal for 15 years.

In 1925, he donated four acres of prime real estate that he owned in the heart of the town for the construction of the Municipal High School.

He recently received the Life Time Achievement Award for his contributions including the development of a Cotton variety named "Narasimha."

He is the President of "Nandi Rythu Samakya," which provides advice and help to poor and marginal farmers in sustainable cultivation practices.

His organization also serves the needs of tribal people (Chenchu tribe) in the Nallamala Forest spanning Kurnool and Prakasam districts in Andhra Pradesh.

Every month a doctor and supporting staff visit each of the thirty settlements and provide health checkups and free medicines for them.
