Tziporah Malka 'Tzipi' Livni (born July 8, 1958, in Tel Aviv, Israel) is a former Israeli politician, diplomat, lawyer, and advocate known for her centrist, peace-oriented views and strong support for a two-state solution to the Israeli-Palestinian conflict. Born into a prominent right-wing Revisionist Zionist family, her parents' marriage on May 15, 1948, was the first in the newly declared State of Israel, receiving special wartime dispensation. Her father served as a Likud Knesset member from 1974 to 1984, and both parents were active in the Irgun, a Zionist paramilitary group. Livni served in the Israel Defense Forces from 1976 to 1979 as a lieutenant and instructor at the officers' training school, followed by a stint in the Mossad intelligence agency. She earned a Bachelor of Laws from Tel Aviv University in 1984 and practiced law for over a decade, specializing in commercial, constitutional, and real-estate law, before entering politics in 1996 as a Likud party member.

Livni rose through the ranks to hold several key government positions, including Minister of Justice (2006–2007 and 2013–2014), Minister of Foreign Affairs (2006–2009), and other cabinet roles. She led the centrist Kadima party from 2008 to 2012, serving as opposition leader, and founded and chaired the Hatnua party from 2012 to 2019, serving as its chief executive, establishing herself as a key figure in Israeli opposition politics. She was co-leader of the Zionist Union in 2015 and briefly served as acting Prime Minister in 2013. As a peace advocate, Livni has been a leading voice for negotiations ensuring Israel's security as a Jewish and democratic state, actively participating in international discussions and U.S. diplomacy—such as the Annapolis Conference—and criticizing extremism on both sides of the conflict, including opposition to Netanyahu's extremes. She played a significant role in peace negotiations, including leading talks in 2013–2014 under U.S. mediation. She has argued for collaboration with moderate Palestinian elements and the Palestinian Authority to resolve national rather than religious dimensions of the dispute, maintaining moderate positions on Palestinian issues.

Throughout her career, Livni transitioned from her family's right-wing roots to a centrist ideology, emphasizing diplomacy and legal frameworks in Israeli governance. Her roles in peace negotiations and high-level diplomacy have positioned her as a key figure in Israel's political landscape, though she faced challenges in sustaining party leadership amid shifting coalitions. After leaving electoral politics in 2019, she continues public engagement through social media and commentary. Married to Naftali Livni, she maintains an active public presence through social media and continues to engage in political discourse, including debates on the two-state solution.
