English poet whose works relate intensely personal matters in a plainspoken, traditional, and objective style and whose verse frequently reflects her devout Roman Catholicism and her love of Italy.

Jennings was educated at Oxford High School and St. Anne's College, Oxford. Her first pamphlet, Poems, appeared in 1953, followed by A Way of Looking (1955), which won her a Somerset Maugham Award and enabled her to visit Italy. Song for a Birth or a Death (1961) marked a new development, with its confessional tone and more savage view of love. Some of the best of her later poems concern her nervous breakdown and its aftermath, such as those collected in Recoveries (1964) and The Mind Has Mountains (1966). Other works include The Animals' Arrival (1969), Lucidities (1970), Relationships (1972), Extending the Territory (1985), and Familiar Spirits (1994). A translation, The Sonnets of Michelangelo (1961), was revised in 1969. She also published poetry for children. In 1992 Jennings was made a Commander of the British Empire.
