Jan Mark (22 June 1943 – 16 January 2006) was a British writer best known for children's books. In all she wrote over fifty novels and plays and many anthologised short stories. She won the annual Carnegie Medal from the Library Association, recognising the year's best children's book by a British subject, both for Thunder and Lightnings (1976) and for Handles (1983). She was also a "Highly Commended" runner up for Nothing To Be Afraid Of (1980). She has won the Carnegie Medal twice, and no one has won three Carnegies.[a]
Janet Marjorie Brisland was born in Welwyn Garden City, Hertfordshire and was raised and educated in Kent. She was a secondary school teacher between 1965 and 1971 and became a full-time writer in 1974. She was married once and divorced, and was survived by her daughter Isobel and son Alex.
Mark is known for acutely observed short stories that are concise and show an imaginative use of language. She also wrote novels about seemingly ordinary children in contemporary settings, such as Thunder and Lightnings, as well as science fiction novels set in their own universes with their own rules, such as The Ennead. Her last works include the young adult novels The Eclipse of the Century and Useful Idiots.
The title of Thunder and Lightnings, a story set in rural Norfolk, is a reference to the British RAF jet fighter the English Electric Lightning and in turn inspired the name of a website documenting Cold War British military aircraft.
Jan Mark was popular in Flanders, Belgium, where she participated in an educational project to stimulate teachers of English into using teenage fiction in the classroom. Her Flemish friends devoted a website to her and to her work.

Since 1995 there are usually eight books on the Carnegie shortlist.
CCSU lists 32 "Highly Commended" runners up for the Carnegie Medal from 1966 to 2002 but only three before 1979 when the distinction became approximately annual. From 1979 there were 29 "HC" books in 24 years including Mark alone in 1980.
• No one has won three Carnegies. Among the seven authors with two Medals, six were active during 1966–2002 and all wrote at least one Highly Commended runner up, led by Anne Fine with three and Robert Westall with two.
