The 1957 Indian general election polls in Tamil Nadu were held for 34 seats in the state. The result was a victory for Indian National Congress winning 24 out of 34 seats. The major opposition for INC, the CPI, managed to only win 2 seats. This election also saw the entry of Dravida Munnetra Kazhagam in their first national election, who ended up winning 2 seats. Due to the nonrecognition of state parties such as the DMK, they were grouped under independent parties, which won a total of 8 seats.
Changes in seats and votes are calculated based on the seats and votes won and polled in Tamil-speaking areas of Madras (only) during general elections held in 1951
Independent parties are local state parties (like DMK), that are unrecognised nationally
