Sanna Marin is the Former Prime Minister of Finland (2019-2023) and the former leader of the Finnish Social Democratic Party. Appointed at the age of 34, Marin served as the youngest Prime Minister of the world when taking office in 2019. She also made history as the longest-serving woman prime minister of Finland, leading a coalition government entirely headed by women. During Sanna Marin’s term, she led Finland through the COVID-19 pandemic, and her government implemented many progressive reforms addressing climate change, social justice and equality, including world's most ambitious climate laws aiming for carbon neutrality by 2035 and progressive family leave reform. She helped the country navigate neighboring Russia’s devastating full-scale invasion of Ukraine, and Finland’s rapid joining of NATO – the swiftest entry for any country in the alliance’s history. Following her term as Prime Minister, Marin joined the Tony Blair Institute for Global Change, and specializes in topics of geopolitics, strategic autonomy, climate change, and female leadership. Her new book, Hope in Action: A Memoir about the Courage to Lead, is coming out on November 4, 2025. Marin has been actively engaged in politics since 2006. She has spoken at Davos AM23, the Lowy Institute, the Munich Security Conference, and for New York University’s 2023 Commencement, among others.
