The Congress of the Philippines is the legislature of the national government of the Philippines. It is bicameral, composed of a lower body, the House of Representatives, although colloquially the term "Congress" commonly refers to just the latter, and an upper body, the Senate. The House of Representatives meets in the Batasang Pambansa in Quezon City while the Senate meets in the GSIS Building in Pasay.

The government of the Philippines has three interdependent branches: the legislative, executive, and judicial branches. The Philippines is governed as a unitary state under a presidential representative and democratic constitutional republic in which the president functions as both the head of state and the head of government of the country within a pluriform multi-party system.
