The seventh legislative assembly election to Tamil Nadu was held on May 28, 1980. Election was held two years before the end of the term of M. G. Ramachandran administration as it was dissolved by the then President of India Neelam Sanjiva Reddy. Dravida Munnetra Kazhagam allied with the Indian National Congress (Indira) and Anna Dravida Munnetra Kazhagam with Janata Party. Despite their victory at the 1980 Lok Sabha polls, DMK and Indira Congress failed to win the legislative assembly election. ADMK won the election and its leader and incumbent Chief Minister, M. G. Ramachandran was sworn in as Chief Minister for the second time. He became the first leader since K. Kamaraj to win a re-election as a Chief Minister.
