Taimi Tellervo Koivisto (née Kankaanranta; born 2 January 1929)[1] is a Finnish politician and the former First Lady of Finland from 1982 to 1994.

[2] Koivisto was born to a farmer's family in the Western Finnish municipality Punkalaidun, in the Satakunta region.

In the late 1960s and the early 1970s Koivisto was active in the feminist organization Yhdistys 9, and worked as a columnist for the news magazine Suomen Kuvalehti 1968–1972.

During her husband's presidential term, Koivisto was more focused on social issues and charity work than on her ceremonial position of the First Lady.

[2] In her 1999 autobiography Koivisto wrote openly of her depression which was launched at the age of 70 by her childhood memories of school bullying.
