Kristrún Mjöll Frostadóttir was born on 12 May 1988 in Reykjavík, the capital of Iceland. She is the daughter of ethnographer Frosti Fífill Jóhannsson and physician Steinunn Guðný H. Jónsdóttir. Frostadóttir began her education in Reykjavík and graduated from Reykjavík Junior College (Menntaskólinn). She continued her higher education at the University of Iceland, earning a bachelor’s degree in economics. She then obtained two separate master’s degrees: one in international relations from the Jackson School of Global Affairs at Yale University and another in economics from Boston University.

Frostadóttir began her professional career in journalism, working for the business newspaper Viðskiptablaðið. She soon joined the analysis department of Arion Bank and advanced her career internationally, serving as a specialist economist at Morgan Stanley in New York and later in London. After returning to Iceland, she began working as chief economist at the Icelandic Chamber of Commerce in 2017 and became chief economist at Kvika Bank in 2018, holding this position until 2021. During the same period, she also taught courses in economic policy at the University of Iceland.

In 2021, Frostadóttir left her economic role to enter active politics, running as a candidate for Samfylkingin (Social Democratic Alliance) in the Reykjavík South constituency. She was elected to the Alþingi, Iceland’s parliament, in the September 2021 elections. After her election, she organized public town halls across the country to engage directly with citizens, stating that this approach allowed her to better understand the living conditions and political expectations of different segments of society.^【2】

Following the announcement in summer 2022 by Logi Einarsson, who had led Samfylkingin since 2016, that he would not seek re-election, Frostadóttir declared her candidacy for general secretary at a party meeting held on 19 August 2022 at the Iðnó building in Reykjavík. She described this decision as the culmination of a long period of reflection, asserting her belief that Iceland could be better governed. She emphasized prioritizing solidarity and empathy over individualism in politics and pledged to deliver concrete solutions in housing, healthcare, transportation, and social security.^【3】

On 28 October 2022, at the party congress held at the Grand Hótel, Frostadóttir, as the sole candidate, was elected General Secretary of Samfylkingin with 94.59 percent of valid votes. A Gallup poll conducted prior to the election recorded the party’s support rising significantly from 9.9 percent in the 2021 elections to 16.3 percent.^【4】

In October 2024, disagreements over immigration, energy policy, and the economy led to the collapse of the coalition government led by Prime Minister Bjarni Benediktsson, prompting the decision to hold early general elections. According to the final results of the elections held on 30 November 2024, Samfylkingin won 15 seats in the 63-seat Alþingi with 20.8 percent of the vote, becoming the party with the most votes. The conservative Independence Party received 19.4 percent of the vote and won 14 seats, while the centrist Viðreisn (Liberal Reform Party) secured 15.8 percent of the vote and 11 seats. This result represented more than double the vote share Samfylkingin had received in the 2021 elections.^【5】 

On 3 December 2024, Frostadóttir was tasked by the President with forming a government. On the same day, she brought together Þorgerður Katrín Gunnarsdóttir, leader of Viðreisn, and Inga Sæland, leader of Flokkur fólksins, for talks in the Alþingi. The meeting focused on ensuring economic stability, reducing inflation and interest rates, and decreasing the number of ministries. Formal coalition negotiations began on 4 December 2024, with the resulting coalition expected to control 36 of the 63 seats in the Alþingi.^【6】

On 21 December 2024, at a ceremony in Hafnarfjörður, the coalition program of Samfylkingin, Viðreisn, and Flokkur fólksins was presented to the public, and Frostadóttir was formally sworn in as Prime Minister of Iceland. The new government includes a total of 11 ministers: four from Samfylkingin, four from Viðreisn, and three from Flokkur fólksins.^【7】

In announcing the government program, Frostadóttir noted that reducing the number of ministries from 12 to 11 would achieve significant savings. As part of this restructuring, the Ministry of Trade and Tourism was merged into the Ministry of Food and transformed into the Ministry of Industry. The Ministry of Culture was combined with the Ministry of Higher Education, Trade and Innovation to form the Ministry of Culture, Innovation and Universities. Housing policy was transferred from the Ministry of Infrastructure to the Ministry of Social Affairs. As a result, the Ministry of Infrastructure became the Ministry of Transport and Local Government, and the Ministry of Social Affairs and Labour became the Ministry of Social Affairs and Housing.

In the new cabinet, Viðreisn leader Þorgerður Katrín Gunnarsdóttir was appointed Minister of Foreign Affairs, and Flokkur fólksins leader Inga Sæland became Minister of Social Affairs and Housing.^【8】 

From Samfylkingin, Jóhann Páll Jóhannsson was appointed Minister of Environment, Energy and Climate; Logi Már Einarsson became Minister of Culture, Innovation and Universities; and former Director General of Health Alma Möller was named Minister of Health. From Viðreisn, Daði Már Kristófersson, who entered parliament from outside, assumed the role of Minister of Finance and Economy; Hanna Katrín Friðriksson became Minister of Industry; and Þorbjörg Sigríður Gunnlaugsdóttir took office as Minister of Justice. From Flokkur fólksins, Eyjólfur Ármannsson was appointed Minister of Transport and Local Government, and Ásthildur Lóa Þórsdóttir became Minister of Education and Children’s Affairs. Þórunn Sveinbjarnardóttir was elected Speaker of the Alþingi.^【9】

Speaking at a joint press conference in Warsaw on 26 February 2026 with Polish Prime Minister Donald Tusk, Frostadóttir announced that a national referendum would be held in the coming months to determine whether Iceland should restart accession negotiations with the European Union. She reiterated her view that this critical foreign policy decision must ultimately rest with the will of the Icelandic people.^【10】 

Iceland’s relations with the EU have been at a standstill since 2015, when its 2009 application for membership was withdrawn due to disagreements over fishing quotas and national sovereignty. While the country continues to participate in the European Economic Area and the Schengen Area, domestic debate persists regarding the stability of the Icelandic króna and rising inflation.

At the NATO Summit held in The Hague, Netherlands, on 25 June 2025, member states agreed to raise their defense spending target to 5 percent of gross domestic product. During the summit, Frostadóttir met with U.S. President Donald Trump, U.S. Secretary of State Marco Rubio, and Greek Prime Minister Kyriakos Mitsotakis.^【11】

Speaking at a joint press conference following the Nordic Council Summit held in Stockholm, Sweden, Frostadóttir affirmed Iceland’s active support for Ukraine, emphasizing that while her country has no standing army, it is an active member of NATO. European Commission President Ursula von der Leyen also attended the summit.^【12】

Attending the 36th NATO Summit of Heads of State and Government held in Ankara, the capital of Türkiye, on 7–8 July 2026, Frostadóttir participated on the evening of 7 July in an official state dinner hosted by President Recep Tayyip Erdoğan and his wife Emine Erdoğan for heads of state and government and their spouses at the Beştepe Presidential Complex.^【13】

Frostadóttir’s visible appreciation for the architecture of the Presidential Complex generated widespread attention on social media. In remarks to the press during the summit, she praised Türkiye’s hospitality and the preparatory efforts for the summit. After her official engagements, she visited Ankara Castle, one of the city’s historic landmarks. Inside the castle, she sampled local cuisine at a restaurant, observed the cityscape from the castle walls, and engaged in conversation with local shopkeepers.^【14】

Kristrún Frostadóttir is married to Einar Bergur Ingvarsson. The couple has two daughters, born in 2019 and 2023. Balancing her political duties with family life, Frostadóttir supports programs aimed at strengthening Iceland’s welfare state and family policies.
