The 2016 Senate election in the Philippines occurred on May 9, 2016 to elect one-half of the Senate. The senators elected in 2016, together with those elected in 2013, comprise the Senate's delegation in the 17th Congress.
The proclamation of all the 12 senators was done ten days after Election Day, on May 19. three incumbents that ran successfully defended their seats, while four former and five new senators were elected.
Senators are elected on a nationwide, at-large basis via plurality-at-large voting system. A voter has twelve votes: the voter can vote for up to twelve candidates. Votes are tallied nationwide and the twelve candidates with the highest number of votes are elected to the Senate. The Commission on Elections administers elections for the Senate, with the Senate Electoral Tribunal deciding election disputes after a Senator has taken office.
