Sylvi Kekkonen (née Uino; 12 March 1900 — 2 December 1974) was a Finnish writer and the longest-serving First Lady of Finland.

[3] In 1926, she married Urho Kekkonen; they had met while working at a central law enforcement agency Etsivä keskuspoliisi (now the Finnish Security Intelligence Service).

[1][5] She was also active as a patron of various events and other initiatives,[1] although in later life her health deteriorated and she was forced to cut down on her public appearances.

[5] She is the longest-serving First Lady, with 18 years in the role, and is likely to remain so as the tenure of Presidents of Finland is now limited to a maximum of two consecutive six-year-terms.

[7][5] To commemorate her, an annual literary symposium, Sylvi Symposiumi, has been held since 2000 in Pieksämäki,[3] where there is also a park named after her.
