Kathleen Jessie Raine CBE (14 June 1908 – 6 July 2003) was an English poet, critic and scholar, writing in particular on William Blake, W. B. Yeats and Thomas Taylor.

Raine spent part of World War I, 'a few short years', with her Aunty Peggy Black at the manse in Great Bavington, Northumberland.

[citation needed] Raine was educated at County High School, Ilford, and then read natural sciences, including botany and zoology, on an Exhibition at Girton College, Cambridge, receiving her master's degree in 1929.

The title of Maxwell's most famous book Ring of Bright Water, subsequently made into a film of the same name starring Bill Travers and Virginia McKenna, was taken from a line in Raine's poem "The Marriage of Psyche".

The relationship with Maxwell ended in 1956 when Raine lost his pet otter, Mijbil, indirectly causing the animal's death.

[7] From 1939 to 1941, Raine and her children shared a house at 49a Wordsworth Street in Penrith with Janet Adam Smith and Michael Roberts and later lived in Martindale.

There were many subsequent prose and poetry works, including her scholarly masterwork, the two-volume Blake and Tradition that was published in 1969 and derived from the A.W.

[9] Raine was the first woman lecturer in the history of the series[10] and her research demonstrated the antiquity, coherence and integrity of William Blake's philosophy, refuting T S Eliot's assertion to the contrary (Collected Essays, 1932).

The three books were originally published separately and later brought together in a single volume, entitled Autobiographies (in conscious imitation of Yeats), edited by Lucien Jenkins.

She was a frequent contributor to the quarterly journal Studies in Comparative Religion, which dealt with religious symbolism and the Traditionalist perspective.

Richard Rodney Bennett's Spells (1974–75), a work for soprano, chorus, and large orchestra, is set to texts by Raine.
