List of longest-serving senators of the Philippines

Tito Sotto is the longest-serving member of the Philippine Senate in history, with a cumulative tenure of 24 years, 234 days.
Lorenzo Tañada served the longest continuous term in the Senate, holding office for 24 straight years from 1947 to 1971.
Loren Legarda is the longest-serving female member of the Senate in history (21 years, 234 days).

This list of longest-serving senators of the Philippines includes senators who have served for at least 12 years (a total period exceeding the usual limit of two six-year terms) in the Senate of the Philippines.

For senators elected in 1941, only the days from June 9, 1945, after the First Commonwealth Congress first convened, are counted, excluding the days they were unable to serve due to the Japanese occupation of the Philippines and the outbreak of World War II.

Time in the Philippine Senate

Lorenzo Tañada currently holds the record for the longest uninterrupted term in the Philippine Senate, serving from 30 December 1947 to 30 December 1971—a total of 8,766 days (24 years) of continuous service.[1] Franklin Drilon is tied with Tañada in terms of total length of service, but he served four non-consecutive terms.[2] Tito Sotto assumed office for his fifth term on 30 June 2025 and became the longest-serving senator, in Philippine history overall, surpassing Tañada.[3]
