Margaret Deland (born Margaretta Wade Campbell; February 23, 1857 – January 13, 1945) was an American novelist, short story writer, and poet.

Her mother died due to complications from the birth, and she was left in the care of an aunt named Lois Wade and her husband Benjamin Campbell Blake.

[2] Deland and her husband moved to Boston, Massachusetts and, over a four-year span, they took in and supported unmarried mothers at their residence at 76 Mount Vernon Street on Beacon Hill.

[3] It was in this home that Canadian actress Margaret Anglin visited in 1909, and the two women reviewed Deland's manuscript for The Awakening of Helena Richie.

Anglin reported "I never spent a pleasanter time than I did while Mrs. Deland and I chugged up and down the little Kennbunkport [sic] River in a boat, talking over the future of Helena Richie.

[10] Her 'Old Chester' books, based on her early memories of the Pittsburgh communities where she grew up — including Maple Grove and Manchester — were also popular.
