The 2004 election of members to the Senate of the Philippines was the 28th election to the Senate of the Philippines. It was held on Monday, May 10, 2004, to elect 12 of the 24 seats in the Senate. The major coalitions that participated are the Koalisyon ng Katapatan at Karanasan sa Kinabukasan, composed of parties that support the candidacy of President Gloria Macapagal Arroyo, and the Koalisyon ng Nagkakaisang Pilipino, composed of parties that support the candidacy of film actor Fernando Poe Jr. coalition. The Alyansa ng Pag-asa was a minor coalition made up of Aksyon Demokratiko and Partido para sa Demokratikong Reporma–Lapiang Manggagawa. K4 won seven seats, while the KNP won the remaining five contested seats.

The elections were notable for several reasons. This election first saw the implementation of the Overseas Absentee Voting Act of 2003 (see Wikisource), which enabled Filipinos in over 70 countries to vote.

Philippine Senate elections are via pluraity block voting, with the entire country as an at-large "district". Each voter has 12 votes, and can vote for up to 12 candidates. Seats up were the seats last contested in 1998.

This election has seen strong shifts of alliances and new parties as candidates switched allegiances. The two major coalitions seen in this elections were the pro-administration K-4 and the KNP as the "united opposition".

The Koalisyon ng Katapatan at Karanasan sa Kinabukasan (Coalition of Honesty and Experience for the Future) was the remnant of the People Power Coalition that was formed following the ascendancy of President Gloria Macapagal-Arroyo to power. Arroyo was seeking a full term under the K4 coalition with Senator Noli de Castro, an independent, popular politician, as her running mate. The leading party in this coalition is the ruling Lakas—Christian Muslim Democrats, of which Arroyo was a member. Other parties under this coalition are Liberal Party, Nacionalista Party, Nationalist People's Coalition and People's Reform Party.

The Koalisyon ng Nagkakaisang Pilipino (Coalition of United Filipinos) was the coalition of the "united opposition". Its presidential and vice-presidential candidates were Fernando Poe Jr. and Senator Loren Legarda. The leading parties of this coalition were Laban ng Demokratikong Pilipino—Angara wing, PDP–Laban, and Pwersa ng Masang Pilipino. The LDP split had been caused by stubbornness between presidentiables Poe and Senator Panfilo Lacson, especially with Poe's support from former President Joseph Estrada and former First Lady Imelda Marcos. The other major party under this coalition was Estrada's Partido ng Masang Pilipino.

The third major coalition running in this election is the Alyansa ng Pag-asa (Alliance of Hope), This coalition fielded Raul Roco for president and Herminio Aquino for vice-president. The three major parties supporting this coalition were Roco's Aksyon Demokratiko, former National Defense Secretary Renato de Villa's Partido para sa Demokratikong Reporma, and former Cebu Governor Lito Osmeña's Probinsya Muna Development Initiative. These three parties bolted from the People Power Coalition.

Bangon Pilipinas (Rise Up, Philippines) is the political party of Bro. Eduardo Villanueva. It consisted mostly of volunteers, a majority of whom came from Villanueva's Jesus Is Lord church. Villanueva resigned from the church before submitting his candidacy in order to prevent questions on the separation of church and state.

This coalition led by Makati Representative Butz Aquino was composed of Panfilo Lacson's supporters from LDP party.

This was Eddie Gil's organization. Gil was deemed a nuisance candidate and was disqualified from the presidential race. However, the party qualified for other positions.
