The 2019 election of members to the Senate of the Philippines was the 33rd election of members to the Senate of the Philippines for a six-year term. It was held on May 13, 2019.

The seats of 12 senators elected in 2013 were contested during this election, and the senators that were elected in this election would serve up to June 30, 2025. The winners in this election joined the winners of the 2016 election to form the 18th Congress of the Philippines. The senators elected in 2016 would serve until June 30, 2022.

The Partido Demokratiko Pilipino-Lakas ng Bayan (PDP–Laban), the ruling party headed by President Rodrigo Duterte, led its own administration coalition, the Hugpong ng Pagbabago.

The Senate election was held concurrently with elections to the House of Representatives and local officials above the barangay level.

Hugpong ng Pagbabago won overwhelmingly, while the main opposition coalition, Otso Diretso, was not able to win any seat in the Senate. Hugpong won 9 seats, while the Nationalist People's Coalition, United Nationalist Alliance, and an independent candidate won 1 seat each.

A total of five women, or 42% of the seats contested, won the election, beating the previous record of four female winners set in 2013 (12 seats contested) and in 1992 (24 seats contested).

Senate elections in the Philippines are conducted via the plurality-at-large voting system, where the entire country is one at-large "district". Each voter can select up to twelve candidates (one vote per candidate), and the twelve candidates with the highest total number of votes are elected.

Senators are term-limited to two consecutive terms, although they are eligible for a third non-consecutive term. Only half of the seats are up in every senatorial election. The winning senators succeeded those elected in 2013, and joined those elected in 2016 in the 18th Congress.
