Sara Zimmerman Duterte-Carpio (English: /dəˈtɜːrteɪ/, Tagalog: [dʊˈtɛɾtɛ]; born May 31, 1978), commonly known as Inday Sara, is a Filipino lawyer and politician who is the 15th and current vice president of the Philippines. She is the third female vice president (after Gloria Macapagal Arroyo and Leni Robredo), the third vice president to come from Mindanao, and the youngest vice president in Philippine history. A daughter of the 16th president Rodrigo Duterte, she previously served as the mayor of Davao City from 2016 to 2022, and from 2010 to 2013. She was also Davao City's vice mayor from 2007 to 2010.

Duterte graduated from San Pedro College, initially aiming to pursue a medical career. She attended classes in the College of Law of San Beda College and eventually graduated in San Sebastian College – Recoletos. She was elected as Davao City's vice mayor in 2007, before eventually being elected as the city's mayor from 2010 until 2013, succeeding her father and becoming the youngest and the first female mayor of the city. After her first term ended, she took a brief hiatus, returning to politics in 2016 after being elected again as Davao City mayor and was reelected in 2019. During her second stint as mayor, she initiated the Byaheng DO30 and Peace 911 programs in the city, as well as overseeing the city government's COVID-19 pandemic response. Duterte was also an influential figure in national politics during her father's presidency, forming alliances with several political parties and playing a key role in the ouster of Pantaleon Alvarez as the Speaker of the House of Representatives in 2018.

Duterte ran for the vice presidency in 2022 under Lakas–CMD, becoming the running mate of Bongbong Marcos from the Partido Federal ng Pilipinas under the UniTeam alliance. Their ticket won in a landslide victory, becoming the first running mate pair to win together since 2004, and the first to be elected by a majority since the establishment of the Fifth Republic in 1986. Duterte became the vice president on June 30, 2022, and was inaugurated 11 days earlier in Davao City.

As vice president, Duterte concurrently served as the secretary of education and as vice chairperson of an anti-insurgency task force (NTF-ELCAC) but resigned from both positions on June 19, 2024. Despite her initial electoral alliance with Marcos, political observers have noted her increasing absence from public appearances with the president correlating with a growing rift in the Marcos and Duterte political families. By late August 2024, she has openly admitted her regret to supporting Marcos in the presidential election, while Marcos himself later acknowledged that they have not spoken to each other since she handed in her resignation. After her father was arrested and brought to The Hague in March 2025, her tenure has been characterized by multiple trips abroad that aim to consolidate her family's overseas supporters.

On February 5, 2025, Duterte was impeached by the House of Representatives after concerns were raised regarding her use of confidential funds and her assassination threat against President Marcos, his wife Liza and House Speaker Martin Romualdez. She became the first sitting vice president, as well as the fifth official in Philippine history, to be impeached.

Sara Zimmerman Duterte was born at Davao Doctors Hospital in Davao City on May 31, 1978. She is the second child to then-lawyer later president Rodrigo Duterte and flight attendant Elizabeth Zimmerman. Her great-grandfather was German American, having fled to the Philippines from the United States.

Growing up in what she called a "broken family", she has spoken of her "love-hate relationship" with her father when she was a student due to her disapproval for his womanizing tendencies and late night habits. Once he left his wife Elizabeth in the 1990s, Sara stayed with her mother, and up to the time she was mayor, Sara considered her relationship with her father as "not very close". Despite this, Rodrigo considered Sara to be his favorite child, and placed high value on the education she and her brothers received.

Duterte attended San Pedro College, majoring in BS Respiratory Therapy, and graduated in 1999; in her inaugural speech as mayor of Davao City, Duterte said she originally wanted to be a pediatrician instead of a politician. She later took up a law degree from San Beda College but transferred to the San Sebastian College – Recoletos, where she graduated in May 2005. In 2005, Duterte passed the Philippine Bar Examination. She then worked for a few months as a court attorney at the office of Supreme Court Associate Justice Romeo Callejo Sr.
