The Senate of the Philippines is the upper house of the Philippine Congress. The Senate is composed of 24 senators, each elected to a six-year term, renewable once, under plurality-at-large voting: on each election, the voters vote for up to twelve candidates, with the twelve candidates the highest number of votes being elected in.

Prior to 1916, the Philippine Assembly, from 1935 to 1941 the National Assembly, and from 1978 to 1986 the Batasang Pambansa (National Legislature) were the sole houses of the legislature. In periods where the legislature was bicameral, the upper house has always been called the "Senate." From 1972 to 1978 and from 1986 to 1987, the president possessed legislative powers.

As of June 2025, a total of 254 officeholders have served in the Senate (including those currently serving).

List Senators' terms are always for six years. The exceptions and details are:

For those elected under the Jones Law, terms start on election day and end six years later. In the first legislature, the candidate per district that places first shall serve for six years, and those who placed second shall serve three years. A new constitution was ratified after the 10th Legislature, abolishing the Senate. Senators' terms ended once the 1935 constitution was put into effect on September 16, 1935. For those elected under the 1935 Constitution as amended, terms start on December 30 after their election and end December 30 six years later. For those elected in 1941, the first Congress convened on July 4, 1945, or almost four years from when the winning candidates' terms started on December 30, 1941. As no senatorial elections were held from 1941 up to that time, it was decided by lot who shall serve until 1946 and who shall serve until 1947. President Ferdinand Marcos declared martial law on September 23, 1972, while the Senate was in recess. He prevented Congress from convening again, and a new constitution approved in 1973 abolished the Senate. For those elected under the 1987 Constitution, terms start on June 30 after their election and end June 30 six years later. For those elected in the first Congress after the ratification of the constitution, the senators served from June 30, 1987, to June 30, 1992. For those elected in the second Congress after the ratification of the constitution, the senators that finished 1st to 12th in the 1992 election served from June 30, 1992, to June 30, 1998. Those who finished 13th to 24th served from June 30, 1992, to June 30, 1995.
