The first legislative assembly election for the Madras Presidency was held in February 1937, as part of the nationwide provincial elections in British India. The Indian National Congress obtained a majority by winning 159 of 215 seats in the Legislative Assembly. This was the first electoral victory for the Congress in the presidency since elections were first conducted for Madras Legislative Council in 1920. The Justice Party which had ruled the presidency for most of the previous 17 years was voted out of power. The assembly was constituted in July 1937 and C. Rajagopalachari (Rajaji) became the first Congress Prime Minister of Madras.

The Madras Presidency or Madras Province, officially called the Presidency of Fort St. George until 1937, was an administrative subdivision (province) of British India and later the Dominion of India. At its greatest extent, the presidency included most of southern India, including all of present-day Andhra Pradesh, almost all of Tamil Nadu and parts of Kerala, Karnataka, Odisha and Telangana in the modern day. The city of Madras was the winter capital of the presidency and Ooty was the summer capital.
