Kathleen Mary Norton (née Pearson; 10 December 1903 – 29 August 1992), known professionally as Mary Norton, was an English writer of children's books. She is best known for The Borrowers series of low fantasy novels (1952 to 1982), which is named after its first book and, in turn, the tiny people who live secretly in the midst of contemporary human civilisation. Norton won the 1952 Carnegie Medal from the Library Association, recognising The Borrowers as the year's outstanding children's book by a British author. For the 70th anniversary of the Medal in 2007 it was named one of the top ten winning works, selected by a panel to compose the ballot for a public election of the all-time favourite. Norton's novels The Magic Bed Knob; or, How to Become a Witch in Ten Easy Lessons and Bonfires and Broomsticks were adapted into the 1971 Disney film Bedknobs and Broomsticks.

She married Robert Charles Norton on 4 September 1926 and had four children, two boys and two girls; her son, also named Robert Norton, became a printer and Microsoft executive. Her second husband was Lionel Bonsey, whom she married in 1970. She began working for the War Office in 1940 before the family moved temporarily to the United States. She began writing while working for the British Purchasing Commission in New York City during the Second World War.
