India is a vast, diverse and politically vibrant country and holding the position of the Prime Minister of the nation is more than just administrative responsibilities but also managing public expectations, national identity and creating a better future for the nation. Since independence in 1947, India has seen a total of 14 Prime Ministers. From freedom fighters and economists to political strategists and mass leaders these leaders took the position and left indelible marks throughout their tenures.

The first Prime Minister of India, Jawaharlal Nehru laid the foundation of a modern and secular nation. He was then followed by Indira Gandhi who helped shape the political discourse in 1970. Later, Manmohan Singh took the leadership position and his quiet yet steady leadership marked a decade of economic and global repositioning. 

Now recently, Narendra Modi has emerged as one of the most important political figures and as of July 2025, has officially become the second longest-serving Prime Minister in India’s history, overtaking Indira Gandhi’s record for an unbroken tenure. Here is a list of the longest-serving Prime Ministers in India.
