Katri Briitta Ilona Kulmuni (born 4 September 1987) is a Finnish politician who served as the 35th deputy prime minister of Finland and the leader of the Centre Party between 2019 and 2020.

[6] Katri Kulmuni is married to lawyer Jyrki Peisa, who works as Director at the Finnish Forest Industries.

From December 2010 to June 2011, Kulmuni worked as Press Assistant to Minister for Foreign Trade and Development Paavo Väyrynen.

[11] On 7 September 2019, Kulmuni defeated Antti Kaikkonen in the leadership election of the Centre Party.

[1] Subsequently, Kulmuni justified her resignation by saying that she had to bear overall responsibility for what happened when she learned that the training service was unreasonably expensive.

I also paid the training bills from my own funds, even though there was no legal obligation to do so," Kulmuni wrote in summer 2024.

Besides, Kulmuni justified her candidacy by her willingness to restore the lost support of the Centre Party.

[22] Shortly after her 2019 appointment as finance minister, Kulmuni caused controversy when she posted an informal Instagram poll on whether the government should allow Finnish women with links to Islamic State to return from Syria, or just their children.

[31] It was claimed in the Finnish press that Prime Minister Sanna Marin did not get along well with Katri Kulmuni and called her a nuisance.
