The Philippines' at-large senatorial district is the at-large representation of the Philippines to elect its Senate. Currently it has twelve seats, elected every three years beginning in 1995 in two classes. Previously from 1949 up to 1971, it had eight seats, elected every two years. In several instances as transitory provisions of the constitution, the entire country voted all 24 senators at one election.

For simplicity, these are arranged by name based on the first election year, and not by order of votes.

1935 constitution

The 1935 constitution originally abolished the Senate, creating a unicameral National Assembly. Amendments passed in 1940 reintroduced the 24-member Senate, this time elected nationally. Senators are to have six-year terms, with eight being elected in two years, in a staggered election. Each Congress, in turn has a term of four years, following the term of the House of Representatives.

In 1941, all 24 seats were up, with first eight candidates with the most votes serving for 6 years, the next eight for 4 years, then the following eight for 2 years. Due to the intervention of World War II, this set up was not followed, and the surviving senators that first met in 1945 drew by lots to determine whose 16 seats will be up in the impending 1946 election (delayed from 1943 and 1945), then eight seats on the following 1947 election.

1941 election

Main article: 1941 Philippine Senate election

Listed here are the 16 seats that were first reelected in 1946.

The term of office for senators elected in 1941 started on December 30, 1941. World War II intervened, and Congress did not meet until June 9, 1945. This is the time where most of the senators-elects' tenure started, and ended on May 26, 1946, when the winners of the 1946 election were inaugurated.

These are the 16 seats that were first defended in 1946. For the eight seats also elected in 1941, but first defended in 1947, see Class of 1947.

1973 constitution

President Ferdinand Marcos declared martial law on September 23, 1972, preventing Congress from meeting. A plebiscite for a new constitution was then held in January 1973; it was ratified and abolished the Senate.

In February 25, 1986, Marcos was overthrown after the People Power Revolution. A new constitution was ratified in a 1987 plebiscite, restoring the bicameral Congress.

1987 constitution

The 1987 constitution restored the 24-member Senate, this time having twelve senators with six-year terms elected every three years. In the first election in 1987, in order to align with the term of the president that shall end in 1992, all 24 senators will have five-year terms. In the 1992 election, all 24 seats will again be up, but the first twelve had served for six years (or will first defend those seats in 1998), while the next twelve had served for three years, and shall shall defend their seats in 1995.

Starting in 1992, each Congress has a term of three years, again mirroring the term length of the House of Representatives.
