Siv Jensen (born June 1, 1969, in Oslo, Norway) is a prominent Norwegian politician and economist who served as leader of the right-wing Progress Party (FrP) from 2006 to 2021. She grew up in Oslo as the daughter of a customs officer and a teacher, developed an early interest in politics, and joined the Progress Party's youth wing in 1987 while studying business administration at BI Norwegian Business School (1987–1989), though she did not complete her degree. Before entering full-time politics, she worked as a freelance consultant and in financial roles. Jensen was elected to the Storting (Norwegian Parliament) representing Oslo in 1997 and served until 2021, focusing on economic policy, taxation, and welfare reform. Under her leadership, the FrP achieved significant electoral success, including entering government coalitions. From 2013 to 2020, she served as Norway's Minister of Finance in Erna Solberg's center-right cabinet, overseeing fiscal policy during oil price fluctuations and implementing tax cuts and budget reforms aligned with FrP's liberal economic agenda. In 2021, she stepped down as party leader after the FrP left the government coalition over immigration policy disputes, particularly regarding Syrian refugee returns. Post-leadership, she has transitioned to media and commentary roles, contributing to Norwegian outlets on political and economic issues, and remains influential in conservative circles, advocating for free-market policies and skepticism toward EU integration. Her career has included controversies, such as criticisms of her party's anti-immigration stance and internal party splits, but she is widely recognized for her role in modernizing Norwegian conservatism and her steady hand in economic stewardship.
