The Macavity Awards, established in 1987, are a literary award for mystery writers. Nominated and voted upon annually by the members of the Mystery Readers International, the award is named for the "mystery cat" of T. S. Eliot's Old Possum's Book of Practical Cats. The award is given in four categories—best novel, best first novel, best nonfiction, and best short story. The Sue Feder Historical Mystery has been given in conjunction with the Macavity Awards.
