Mystery Writers of America

The Mystery Writers of America (MWA) is a professional organization of mystery and crime writers, based in New York City.

The organization was founded in 1945 by Clayton Rawson, Anthony Boucher, Lawrence Treat, and Brett Halliday.

It presents the Edgar Award, a small bust of Edgar Allan Poe, to mystery or crime writers every year. It presents the Raven Award to non-writers who contribute to the mystery genre. The category of Best Juvenile Mystery is also part of the Edgar Award, with such notable recipients as Barbara Brooks Wallace having won the honor twice for The Twin in the Tavern in 1994 and Sparrows in the Scullery in 1998, and Tony Abbott for his novel The Postcard in 2009.

John Dickson Carr, who also served as president of the MWA, won a Grand Master Award in 1949 and 1962.
