Mystery Writers of America (MWA) is an 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, which received critical accolades in 2009.
Grand Master Award
The Grand Master Award is the highest honor bestowed by the Mystery Writers of America. It recognizes lifetime achievement and consistent quality. (The award was presented irregularly up to 1978; from 1979 to 2008, it was given to one writer each year. Since 2009, either one or two authors have been honored annually.)
The Raven Awards are recorded in the Edgars Database of the Mystery Writers of America.
