The 1987 election of members to the Senate of the Philippines was the 23rd election to the Senate of the Philippines. It was held on Monday, May 11, 1987. The Philippine Senate was re-instituted following the approval of a new constitution in 1987 restoring the bicameral Congress of the Philippines; earlier, a constitution was approved in 1973 that created a unicameral Batasang Pambansa (parliament) that replaced the bicameral Congress. The last Senate election prior to this was the 1971 election.
