Rakel Liehu (born 3 September 1939) is a Finnish poet, dramatist, and novelist.
Liehu began writing poetry at the age of 11, inspired by the works of women poets such as Aila Meriluoto and has since gone on to publish 13 poetry collections. She has also authored three novels, as well as two plays and various scripts. Her debut poetry collection, Ihmisen murhe on yhteinen (lit. 'The Grief of a Person is Shared'), came out in 1974, and her first novel, Seth Mattsonin tarina ('The Story of Seth Mattson'), in 1976. Her perhaps best-known work is Helene (2003), a novel about the life of the Finnish artist Helene Schjerfbeck, which won the 2004 Runeberg Prize. It formed the basis of the 2020 film of the same name, directed by Antti Jokinen and starring Laura Birn as Schjerfbeck, which was nominated for an award in the feature-length category at the Shanghai International Film Festival. Her latest novel, Valaanluiset koskettimet (2020) ('Whale Bone Keys') is strongly autobiographical. Her other notable works include the novel Punainen ruukku ('Red Pot') (1980), and the essay collection Sininen kala ('Blue Fish') (1999).
