List of chief ministers of Uttar Pradesh

The Chief Minister of Uttar Pradesh is the head of the Government of Uttar Pradesh. As per the Constitution of India, the governor is the state's de jure head, but de facto executive authority rests with the chief minister. Following elections to the Uttar Pradesh Legislative Assembly, the governor usually invites the party (or coalition) with a majority of seats to form the government. The governor appoints the chief minister, whose council of ministers are collectively responsible to the assembly. Given that he has the confidence of the assembly, the chief minister's term is for five years and is subject to no term limits.

On 26 January 1950 Govind Ballabh Pant, premier of United Provinces, became the first chief minister of the newly renamed Uttar Pradesh. Including him, 11 out of UP's 21 chief ministers belonged to the Indian National Congress. Among these is V. P. Singh, a future prime minister of India, as was Charan Singh of the Bharatiya Lok Dal. On ten occasions, most recently in 2002, the state has come under President's rule, leaving the office of chief minister vacant. UP has also had two women chief ministers—Sucheta Kripalani and Mayawati. Akhilesh Yadav of the Samajwadi Party served as the chief minister of Uttar Pradesh from 2012 to 2017; having taken the oath at 38 years of age, he is the youngest person to have held the office. Only three chief ministers completed their official tenure of five years: Mayawati, Akhilesh Yadav, and Yogi Adityanath.

Yogi Adityanath of the Bharatiya Janata Party is serving as the incumbent chief minister since 19 March 2017.
