A senatorial election was held on November 12, 1963 in the Philippines. The 1963 elections were known as a midterm election as the date when the elected officials take office falls halfway through PresidentDiosdado Macapagal's four-year term.
The Liberal Party won control of the chamber after having ten seats out of the 24-member Senate, as the 2-member Grand Alliance (the old Progressive Party) were caucusing with them. Ferdinand Marcos was later elected Senate President a few months after the Senate convened.
