Mary Jane Newill (1860–1947) was an English painter, embroiderer, teacher, book illustrator and stained glass designer associated with the Arts and Crafts Movement.

Fellow students included Charles March Gere, Sidney Meteyard, and Henry Payne.

[3] In 1893, Newill's Babes in the Woods stained glass panel cartoon was displayed at the annual Arts and Crafts Exhibition Society in London, only the second stained glass design by a female artist to be exhibited, and the first by a woman who later became a successful commercial artist.

The drawing was later used by Christopher Whall as an illustration in his influential manual, Stained Glass Work (1905).

"Although her subsequent stained glass work developed in interesting and original ways, it always retained echoes of Image's graphic simplification in the drawing."
