Rodrigo Roa Duterte (English: , Tagalog: [ɾodˈɾiː.ɣo ˈɾoː.ɐ dʊˈtɛːɾ.tɛ] ; born March 28, 1945), also known as Digong, Rody, and by the initials DU30 and PRRD, is a Filipino lawyer and politician who served as the 16th president of the Philippines from 2016 to 2022. He is the chairperson of Partido Demokratiko Pilipino (formerly PDP–Laban), the ruling political party in the Philippines during his presidency. Duterte is the first president of the Philippines to be from Mindanao, and is the oldest person to assume office, beginning his term at age 71.

Born in Maasin, Leyte (now in Southern Leyte), Duterte moved to Davao as a child where his father, Vicente Duterte, served as provincial governor. He studied political science at the Lyceum of the Philippines University, graduating in 1968, before obtaining a law degree from San Beda College of Law in 1972. He then worked as a lawyer and was a prosecutor for Davao City, before becoming vice mayor and, subsequently, mayor of the city in the wake of the 1986 People Power Revolution. Duterte won seven terms and served as mayor of Davao for over 22 years, during which the once crime-ridden city became peaceful and investor-friendly.

Duterte's 2016 presidential campaign led to his election victory. During his presidency, his domestic policy focused on combating the illegal drug trade by initiating the controversial war on drugs, fighting crime and corruption, and intensified efforts against terrorism and communist insurgency. He launched a massive infrastructure plan, initiated liberal economic reforms, streamlined government processes, and proposed a shift to a federal system of government which was ultimately unsuccessful.
