1971 Philippine Senate election
A senatorial election was held on November 8, 1971 in the Philippines. The opposition Liberal Party won five seats in the Philippine Senate while three seats were won by the Nacionalista Party, the administration party; this was seen as a consequence of the Plaza Miranda bombing on August 21, 1971, which wounded all of the Liberal Party's candidates and almost took the lives of John Henry Osmeña and Jovito Salonga. Their terms as senators were cut short as a result of the declaration of martial law by President Ferdinand Marcos on September 23, 1972.

Due to the ratification of a new constitution in 1973, the Senate was abolished and the unicameral parliamentary Batasang Pambansa was instituted. In 1987, a new constitution was approved that reverted to the presidential and bicameral legislative system. This means that this would be the last election for the Senate until the 1987 election.
