20th Congress of the Philippines

The 20th Congress of the Philippines (Filipino: Ikadalawampung Kongreso ng Pilipinas), composed of the Philippine Senate and House of Representatives, is scheduled to convene on July 28, 2025. The 20th Congress will meet during the last three years of Bongbong Marcos's presidency, and will end on June 2028. The convening of the 20th Congress followed the 2025 general elections, which replaced half of the Senate membership and the entire membership of the House of Representatives.

The House of Representatives will continue to meet in the Batasang Pambansa Complex. The Senate will also remain meeting in the GSIS Building before transferring to the New Senate Building in Taguig by 2028.

In the 2025 Philippine midterm election, the administration-backed Alyansa para sa Bagong Pilipinas won the most seats in the Senate but lost ground to groups opposed to President Bongbong Marcos. The DuterTen ticket endorsed by Vice President Sara Duterte and former President Rodrigo Duterte outperformed pre-election surveys and gained seats in the upper chamber.^[1][2] Meanwhile, the KiBam tandem, having ran as an independent opposition aligned with former Vice President Leni Robredo, were both elected, each winning a large share of the vote in upset victories.^[3][4] While Lakas–CMD remained the largest party in the House of Representatives—with 104 of its congressional candidates winning in local races—their share of seats declined from outgoing 19th Congress.^[5]

Political analyst Ronald Llamas interpreted the results as a rejection of the direction of the Marcos administration but not necessarily an approval of the vocal Duterte opposition.^[6] Media outlets attributed the results to Marcos's lack of charisma, his economic policies, the arrest of Rodrigo Duterte, and the impeachment of Sara Duterte.^[7][8]

Among the Senators in the 20th Congress, there are four pairs of siblings—Alan Peter and Pia Cayetano; Raffy and Erwin Tulfo; Jinggoy Estrada and JV Ejercito; and Mark and Camille Villar—the most in Philippine history.^[9] Tito Sotto will become the first Senator to serve a fifth term, becoming the longest-serving member in the history of the chamber.^[10]

In the House of Representatives, seven-term Representative Raymond Mendoza, who has served in every Congress since 2009, is expected to be term-limited after this Congress after having served three uninterrupted terms.^[11]
