Laura Muntz Lyall RCA (June 18, 1860 – December 9, 1930) was a Canadian Impressionist painter, known for her sympathetic portrayal of women and children.

[4] As a young woman, Muntz's interest in art led to her take lessons in painting from William Charles Forster of Hamilton and to live and work at his school.

[4][5] Starting in 1882, she began to take classes at the Ontario School of Art in Toronto where she studied with Lucius Richard O'Brien, and later with George Agnew Reid.

[6] To stretch her limited financial resources, she gave private English lessons, and shared various apartments in Paris from 1893 to 1897 with another student-teacher at the Académie, the American painter, Wilhelmina Douglas Hawley (1860-1958).

[14] When, in 1906, she moved to Montreal to continue her career at 6 Beaver Hall Square, she reached a sizable new audience that regarded her as the premier Canadian portraitist of children.

Her earlier submissions to shows were frequently compared and contrasted with that of her contemporary and friend Florence Carlyle,[4][16] but in time, her work was applauded in its own right, especially for her sympathetic, lucid manner.

[20] In 1930, Muntz was ill and dying of Exophthalmic Goitre brought on partly by overwork and worry about the family responsibilities she had assumed fifteen years earlier.
