Gurmukh Nihal Singh (born 14 March 1895 -22 December 1969) was the first Governor of Rajasthan and second Chief Minister of Delhi from 1955 to 1956 and was a Congress leader. He was the successor of Chaudhary Brahm Prakash and assumed office in 1955 just for one year, as after that States Reorganisation Act, 1956 was passed which made Delhi a Union Territory. Thus, no one was appointed the next CM of Delhi until legislative assembly elections in Delhi were held in 1993, when Union Territory of Delhi was formally declared as National Capital Territory of Delhi by the Sixty-ninth Amendment to the Indian constitution.
