Benjamin "Bibi" Netanyahu (বেঞ্জামিন নেতানিয়াহু) is an Israeli politician and diplomat who has served as the prime minister of Israel since 2022, having previously held the office from 1996 to 1999 and from 2009 to 2021. Netanyahu is the longest-serving prime minister in Israel's history, having served a total of over 17 years.

Born to secular Jewish parents in Tel Aviv, Netanyahu was raised in West Jerusalem and the United States. He returned to Israel in 1967 to join the Israel Defense Forces and served in the Sayeret Matkal special forces as a captain before being honorably discharged. In 1972, he returned to the United States, and after graduating from the Massachusetts Institute of Technology, Netanyahu worked for the Boston Consulting Group before moving back to Israel in 1978 to found the Yonatan Netanyahu Anti-Terror Institute. Between 1984 and 1988 Netanyahu was Israel's ambassador to the United Nations. Netanyahu rose to prominence after election as chair of Likud in 1993, becoming leader of the opposition. In the 1996 general election, Netanyahu became the first Israeli prime minister elected directly by popular vote, its youngest, and the first to have been born after Israel's independence. Netanyahu was defeated in the 1999 election and retired from politics, entering the private sector. He returned and served as minister of foreign affairs and finance, initiating economic reforms, before resigning over the Gaza disengagement plan.

Netanyahu was born in 1949 in Tel Aviv. His mother, Tzila Segal (1912–2000), was born in Petah Tikva in the Ottoman Empire's Mutasarrifate of Jerusalem — her family had migrated from Minneapolis in 1911, having relocated there from Lithuania in the 1870s — and studied law at Gray's Inn, London. His father, Warsaw-born Benzion Netanyahu (né Mileikowsky; 1910–2012), was a historian specializing in the Jewish Golden age of Spain. His paternal grandfather, Nathan Mileikowsky, was a rabbi and Zionist writer. When Netanyahu's father immigrated to Mandatory Palestine, he hebraized his surname from "Mileikowsky" to "Netanyahu", meaning "God has given." While his family is predominantly Ashkenazi, he has said that a DNA test revealed him to have some Sephardic ancestry. He claims descent from the Vilna Gaon.

Netanyahu was the second of three children. He was initially raised and educated in Jerusalem, where he attended Henrietta Szold Elementary School. A copy of his evaluation from his 6th grade teacher Ruth Rubenstein indicated that Netanyahu was courteous, polite, and helpful; that he was "responsible and punctual"; and that he was friendly, disciplined, cheerful, brave, active, and obedient.

Netanyahu returned to the United States in late 1972 to study architecture at the Massachusetts Institute of Technology (MIT). After briefly returning to Israel to fight in the Yom Kippur War, he returned to the United States and, under the name Ben Nitay, completed a bachelor's degree in architecture in February 1975 and earned a master's degree from the MIT Sloan School of Management in 1976. Concurrently, he was studying towards a doctorate in political science, until his studies were broken off by the death of his brother in the Entebbe raid.

Netanyahu was headhunted to be an economic consultant for the Boston Consulting Group in Boston, Massachusetts, working at the company between 1976 and 1978. At the Boston Consulting Group, he was a colleague of Mitt Romney, with whom he formed a lasting friendship. Romney described Netanyahu at the time as "a strong personality with a distinct point of view", and said, "We can almost speak in shorthand ... we share common experiences and have a perspective and underpinning which is similar." Netanyahu said that their "easy communication" was a result of "B.C.G.'s intellectually rigorous boot camp".

Netanyahu was born in Tel Aviv, to Benzion Netanyahu (original name Mileikowsky) and Tzila (Cela; née Segal). His mother was born in 1912 in Petah Tikva, then in Ottoman Palestine, now Israel. Though all his grandparents were born in the Russian Empire (now Belarus, Lithuania and Poland), his mother's parents emigrated to Minneapolis in the United States. He is related to Rabbi Eliyahu of Vilna (the Vilna Gaon) on his paternal side.

Netanyahu's father, Benzion, was a professor of Jewish history at Cornell University, editor of the Encyclopaedia Hebraica, and a senior aide to Ze'ev Jabotinsky, who remained active in research and writing into his nineties.
