# 2025 Philippine senate election

The 2025 Philippine Senate election will be the 35th election of members to the Senate of the Philippines for a six-year term. It will be held on May 12, 2025, within the 2025 general elections.
The seats of the 12 senators elected in 2019 will be contested in this election. The senators that will be elected in this election will serve until 2031, joining the winners of the 2022 election to form the Senate's delegation to the 20th Congress of the Philippines, with the senators elected in 2022 serving until 2028.

## Background
### Electoral system

The Philippines has a 24-member Senate elected at-large. Every three years since 1995, 12 seats are disputed. For 2025, the seats disputed in 2019 will be contested. Each voter has 12 votes, of which one can vote one to twelve candidates, or a multiple non-transferable vote; the twelve candidates with the most votes are elected.
Senators are limited to serving two consecutive terms, although they are eligible for a third (and succeeding) non-consecutive term. Only half of the seats are up in every senatorial election. The winning senators will succeed those elected in 2019, and will join those elected in 2022 to form the 20th Congress.
Each party or coalition endorses a slate of candidates, typically not exceeding a 12-person ticket. A party may also choose to invite "guest candidates" to complete its slate. The party may even include, with the candidates' consent, independent candidates and candidates from other parties as the party's guest candidates. Parties also may form coalitions to endorse a multi-party slate of candidates.
Winning candidates are proclaimed by the Commission on Elections (COMELEC), sitting as the National Board of Canvassers (NBOC). The NBOC usually proclaims senators-elect by batches, if that candidate can no longer fall to worse than twelfth place in the tally. Post-proclamation disputes are handled by the Senate Electoral Tribunal, a body composed of six senators and three justices from the Supreme Court.

## Coalitions
### Alyansa Para Sa Bagong Pilipinas

On May 8, 2024, the Partido Federal ng Pilipinas (PFP) and Lakas–CMD signed an alliance agreement at the Manila Polo Club in Makati to form the Alyansa Para sa Bagong Pilipinas for the 2025 general elections. House Speaker Martin Romualdez remarked that the formation of the alliance created the "most powerful political force in our country today", noting the positioning of the PFP as the de facto ruling party in the country and Lakas' status as the largest political party in the House of Representatives.
Two days later, former Senator Manny Pacquiao announced his senatorial candidacy as a member of the alliance while remaining a member of PROMDI.

### Liberal Party

At a forum of the Foreign Correspondents Association of the Philippines (FOCAP) on February 22, 2024, Liberal Party spokesperson and former Senator Leila de Lima announced that the party plans to field senators Bam Aquino and Francis Pangilinan, as well as human rights lawyer and Chel Diokno, as its senatorial candidates in the upcoming election.
