Demons by Daylight is a collection of stories by English author Ramsey Campbell. Released in 1973, it was the author’s second short story collection, after The Inhabitant of the Lake and Less Welcome Tenants. Like the earlier book, it was published by Arkham House.

Campbell had completed work on the stories for it by 1968, and it was scheduled for publication in 1971; however, due to the 1971 death of editor and Arkham House co-founder August Derleth, the collection was delayed a further two years; it finally saw print in 1973. It was published in an edition totaling 3,472 copies and with dust jacket art by Eddie Jones, commissioned by Campbell.
