The 2004 Indian general election in Kerala were held for 20 Lok Sabha seats in the state. The Communist Party of India (Marxist) led Left Democratic Front (LDF) won 18 seats out of 20 seats in the state. Indian National Congress, who had won 8 seats in the 1999 elections, won one in this election. The other seats were won by Kerala Congress (1), P.C. Thomas's Indian Federal Democratic Party (1), Indian Union Muslim League (1), Janata Dal (Secular) (1), and by an LDF supported Independent candidate (1).

In the aftermath of this election, the then Chief Minister of the state A. K. Antony resigned taking sole responsibility for the INC's poor electoral performance. Despite this, the outside support from the Left Front proved valuable for Congress to have a stable government in the Lok Sabha for the next 5 years.
