Alan Peter Schramm Cayetano (Tagalog:; born October 28, 1970), also known by his initials APC, is a Filipino lawyer, politician, and former diplomat who served as the 33rd president of the Senate from May 2026 until his removal from the post in June 2026. Cayetano had the second-shortest total tenure as Senate president at 23 days. He disputed his ouster from the position on June 3, then conceded to the new majority bloc led by Senate President pro tempore Sherwin Gatchalian on June 17.

A Senator of the Philippines since 2022 and previously from 2007 to 2017, Cayetano has also served as Senate majority leader (2013 to 2016) and has had two stints as Senate minority leader (2010 to 2013 and 2025 to 2026). He served as the 26th speaker of the House of Representatives from 2019 to 2020 and as the 26th secretary of foreign affairs from 2017 to 2018. Since 2021, Cayetano has been an independent politician after leaving the Nacionalista Party.

Born and raised into a political family based in Taguig, Cayetano is the son of former senator and lawyer Rene Cayetano. He entered national politics in 1998 after being elected to the House of Representatives representing Taguig–Pateros, a post he held until 2007, when he was first elected to the Senate. In 2012, he and his sister Pia, were the largest spenders of pork barrel during the height of the pork barrel scandal. He unsuccessfully ran for vice president in the 2016 elections as the running mate of Rodrigo Duterte, who would win the presidency. He resigned from the Senate in 2017 to serve as Duterte's foreign affairs secretary, a role he held until 2018.

In 2019, Cayetano was elected back to the House of Representatives. During this stint, he was elected as speaker of the House. As speaker, he became the chairperson of the organizing committee for the controversial 2019 SEA Games, where P9.5 billion in taxpayer money was used to construct the overpriced main sports venue. He was also appointed chairperson of the Defeat COVID-19 Ad Hoc Committee during the early months of the COVID-19 pandemic in the Philippines, during which media publications ranked the country's response to the pandemic as among the worst in the world. He was later ousted from the House Speakership position by the Velasco bloc.

In 2022, Cayetano was elected back to the Senate for a third nonconsecutive term. On May 11, 2026, Cayetano assisted Senator Ronald dela Rosa in returning to the Senate after six months in hiding, leading to a three-day standoff at the Senate during attempts by law enforcement to arrest dela Rosa under an International Criminal Court warrant. On the same day, he was elected Senate president after he orchestrated the ouster of Senator Tito Sotto from the position amidst the second impeachment of Vice President Sara Duterte. A fake shooting incident allegedly plotted by Cayetano was conducted inside the Senate to help dela Rosa's escape from the law. A few session days later, he was ousted by the Gatchalian-Sotto bloc, becoming second shortest Senate president stint in Philippine history. Cayetano has been embroiled in the flood control controversy in his bailiwick of Taguig City along with illegal reclamation activities in Laguna de Bay worth billions of pesos. He was also named to have at least ₱6.7B in insertions in the 2025 national budget, named the most corrupt budget in Philippine history.
