Membership in Mystery Writers of America brings everything from discounts to professional forums. MWA National has more than 3,000 members internationally, with four kinds of membership available:

Active members are published professional writers of fiction or nonfiction in the crime/mystery/suspense field, a category that includes self-published writers.

Associate members are professionals in allied fields—editors, publishers, agents, booksellers, librarians, etc.

Affiliate members are writers of crime/mystery/suspense fiction who are not yet professionally published, and others with an interest in the genre, including unpaid reviewers and fans or publishers not approved by MWA.

Corresponding members are qualified members who live outside the United States.
