The Bank of Madras was one of the three Presidency Banks of British India, along with the Bank of Bengal and the Bank of Bombay. It was established on 1 July 1843 through the amalgamation of a number of existing regional banks and headquartered in Madras (now Chennai). It was merged with the other Presidency banks in 1921 to form the Imperial Bank of India, which later became the State Bank of India.
