List of political parties in Tamil Nadu

Tamil Nadu has a multi-party system. The Election Commission of India accords recognition to national-level and state-level political parties based upon objective criteria. A recognised political party enjoys privileges like a reserved party symbol, free broadcast time on state-run television and radio, consultation in the setting of election dates, and giving input in setting electoral rules and regulations. Other political parties that want to run in local, state, or national elections must register with the Election Commission of India. The Election Commission of India recognises registered parties as recognised state parties if they meet the relevant criteria following a Lok Sabha or Tamil Nadu Legislative Assembly election. The recognised-party status is reviewed periodically by the Election Commission of India. Prior to the 2016 amendment, which went into effect on 1 January 2014, if a political party failed to meet the criteria in the subsequent Lok Sabha or Tamil Nadu Legislative Assembly election, they lost their status as a recognised party. In 2016, the Election Commission of India announced that such a review would take place after two consecutive elections instead of every election. As a result, a political party must retain its recognised party status even if it fails to meet the criteria in the next election. However, if they fail to meet the criteria in the subsequent election following the next election, they would lose their status.
