A senatorial election in the Philippines was held on November 8, 1955. This was a midterm election, the date when the winners took office falling halfway through President Ramon Magsaysay's four-year term.

Roseller Tarroza Lim was a Filipino politician who served as a member of the Senate and House of Representatives from 1949 to 1963. He also served as Court of Appeals Justice from his appointment in 1973 until his death. Lim was known as the "Great Filibuster," after he filibustered for more than 18 hours in an attempt to prevent the election of Ferdinand Marcos as President of the Senate.
