Lucy Maud Montgomery (November 30, 1874 – April 24, 1942), published as L. M. Montgomery, was a Canadian author best known for a series of novels beginning in 1908 with Anne of Green Gables. She was born at Clifton, Prince Edward Island, and became famous in her lifetime, granting her an international following. Montgomery published 20 novels, 530 short stories, 500 poems, and 30 essays. Most of her novels were set on Prince Edward Island, turning locations within Canada's smallest province into literary landmarks and popular tourist sites, notably Green Gables farm, the inspiration for Prince Edward Island National Park.

Montgomery's work, diaries, and letters have been extensively read and studied worldwide. In 1935, she was made an officer of the Order of the British Empire. The L. M. Montgomery Institute at the University of Prince Edward Island is dedicated to scholarly inquiry into her life, works, culture, and influence. Montgomery married Rev. Ewen Macdonald on July 11, 1911, had three children, and authored close to a dozen books while living in the Leaskdale Manse. The family later moved to Norval, Ontario, in 1926. She died in Toronto on April 24, 1942, and was buried at Cavendish, Prince Edward Island.
