Marghanita Laski was born in Manchester, England, to a prominent family of Jewish intellectuals (Neville Laski was her father, Moses Gaster her grandfather and Harold Laski her uncle), she was educated at Lady Barn House School in Manchester and St Paul's Girls' School in Hammersmith, worked in fashion, then studied English at Somerville College, Oxford  where she was a close friend of Inez Pearn, who was later to become a novelist and marry Stephen Spender and subsequently (following divorce) Charles Madge.
After her son and daughter were born, Laski began writing in earnest; most of her output in the 1940s and 1950s was fiction. She sold the film rights to one novel, Little Boy Lost (1949), about an Englishman on the search for his lost son in the ruins of post-war France to John Mills — however, when the film adaptation was released in 1953, she was upset that it had been turned into a musical starring Bing Crosby. She turned towards non-fiction in the 1960s and 1970s, producing works on Charlotte Mary Yonge, Jane Austen, George Eliot and Rudyard Kipling.
An omnivorous reader, from 1958 onward she became a prolific and compulsive contributor to the Oxford English Dictionary and by 1986 had "carded" around 250,000 quotations, making her (according to Ilan Stavans) "the supreme contributor, male or female, to the OED".
In the 1960s, Laski was the science fiction critic for The Observer. She was a member of the Annan Committee on broadcasting between 1974 and 1977. She joined the Arts Council in 1979, was elected its Vice Chair in 1982, and served as chair of its Literature Panel between 1980 and 1984.
Anthony Boucher described her novella The Victorian Chaise Longue as "an admirably written book, highly skilled in its economic evocation of time, place and character -- and a relentlessly terrifying one." Ecstasy: A Study of Some Secular and Religious Experiences has been compared to The Varieties of Religious Experience by William James in its importance. Tory Heaven, a counterfactual novel depicting a Britain ruled by a rigidly hierarchical Conservative dictatorship and satirising middle-class attitudes towards the Attlee ministry, was described as "wickedly amusing" by Ralph Straus of The Sunday Times, and as "an ingeniously contrived and wittily told tale" by Hugh Fausset of the Manchester Guardian: writing about the book in 2018, David Kynaston called it a "highly engaging, beautifully written novel".
