Benjamin "Bibi" Netanyahu (Hebrew: בִּנְיָמִין "בִּיבִּי" נְתַנְיָהוּ (help·info), also Binyamin Netanyahu, born 21 October 1949) is the Prime Minister of Israel.

He previously held the same position from June 1996 to July 1999 and is currently the Chairman of the Likud Party. Netanyahu is the first (and, to date, only) Israeli prime minister born after the State of Israel's foundation. Netanyahu was Foreign Minister (2002–2003) and Finance Minister (2003–August 2005) in Ariel Sharon's governments, but he departed over disagreements regarding the Gaza Disengagement Plan. He retook the Likud leadership on 20 December 2005. In the 2006 election, Likud did poorly, winning twelve seats. In December 2006, Netanyahu became the official Opposition Leader in the Knesset and Chairman of the Likud Party. In August 2007, he retained the Likud leadership by beating Moshe Feiglin in party elections. Following the 10 February 2009 parliamentary election, in which Likud placed second and right-wing parties won a majority, Netanyahu formed a coalition government. He is the brother of Israeli Special Forces commander Yonatan Netanyahu, who died during a hostage rescue mission, and Iddo Netanyahu, an Israeli author and playwright.

Related to the Rabbi Eliyahu of Vilna (the Vilna Gaon) on his paternal side, Netanyahu was born in Tel Aviv, to Cela (Tsilah; née Segal) and Benzion Netanyahu (original name Mileikowsky). His mother was born in 1912 in Petah Tikva, part of the future British Mandate of Palestine that eventually became Israel. Though all his grandparents were born in Lithuania, his mother's parents emigrated to Minneapolis in the United States. Netanyahu's father is a former professor of Jewish history at Cornell University, a former editor of the Hebrew Encyclopedia, and a former senior aide to Zeev Jabotinsky, who has remained active in research and writing into his 90s. His paternal grandfather was Rabbi Natan Mileikowsky, a leading Religious Zionist rabbi and JNF fundraiser.
