Francis Lillie Pollock (February 4, 1876 – 1957) was an early twentieth-century Canadian science fiction writer. He was born in Huron County, Ontario, Canada in 1876. He wrote 'commercial fiction' under the pseudonym Frank L Pollock and literary fiction under his own name. Some of Pollock's early commercial fiction can be found in The Youth's Companion. He also regularly published short stories and poetry in Munsey's Magazine, The Smart Set, The Atlantic, The Bookman (New York) and The Blue Jay (renamed in 1905 as Canadian Woman Magazine).
The sale of a serialised novel, The Treasure Trail, enabled him to leave his job at the Toronto Mail and Empire in 1907 to pursue a full-time writing career. Pollock's writing career was pursued in tandem with a life of beekeeping. Many of his fictions draw influence from bees. Pollock kept an apiary in Shedden, Ontario and farmed commercially. He and his second wife, Zella Taylor retired to Georgetown, Ontario.
Pollock is the author of the short story "Finis", published in the June 1906 issue of The Argosy magazine, and his work has been anthologized several times. Briefly, "Finis" is the story of a new star that is discovered which turns out to be a new, hotter sun. It is a short hard hitting story which shows a man and woman, who stay up the night to watch the expected new star arise. Though written in 1906, it is set in the future of the mid 20th century. Pollock also wrote several science fiction stories for The Black Cat magazine  as well as sea stories for magazines such as Adventure.
