Antonio Tirol Carpio (born October 26, 1949) is an incumbent Senior Associate Justice of the Supreme Court of the Philippines. He was appointed to the Court by President Gloria Macapagal-Arroyo and assumed office on October 26, 2001, his 52nd birthday.
Born in Davao City, Carpio finished grade school and high school at the Ateneo de Davao University. He obtained his undergraduate degree in Economics from the Ateneo de Manila University in 1970 and his law degree from the University of the Philippines where he graduated valedictorian and cum laude in 1975. He ranked sixth with a rating of 85.70% in the 1975 Philippine Bar Examination. Fresh out of law school, Justice Carpio went into private practice and founded the Carpio Villaraza and Cruz Law firm.  He soon emerged as one of the more prominent and successful legal practitioners in the country. Carpio also taught Tax law, Corporate law, Negotiable Instruments law, and Credit Transactions at the U.P. College of Law from 1983 to 1992.
In 1992, he joined the administration of President Fidel Ramos as Chief Presidential Legal Counsel of the Office of the President. During the presidency of Joseph Estrada, Carpio returned to private practice and penned a regular opinion column published in the Philippine Daily Inquirer.
Carpio was the first appointee of President Gloria Macapagal-Arroyo to the Supreme Court of the Philippines after her assumption into office in January 2001. At 52, he was one of the youngest ever appointees to the Supreme Court.
Senior Associate Justice Carpio is the Chair of the Court's Second Division and Chair of the Senate Electoral Tribunal. He also heads the High Court's Committee on the Revision of the Rules of Court. 
Being the Senior Associate Justice, he assumed the post as the Acting Chief Justice in May 29, 2012 until the President will appoint a new chief justice coming from the list of candidates released by the Judicial and Bar Council although he is a prospect of being the new Chief Justice. He assumed the post after his predecessor, Renato Corona was convicted by the Senate Impeachment court for his failure to disclose in his Statement of Assets, Liabilities, and Net Worth, dollar accounts that led to his removal in office, a penalty authorized by the 1987 Constitution
