Dary Matera (born 1955) is an author who specializes in real-life casebooks. He is from Chandler, Arizona.

Matera grew up in Bangkok, Thailand, and Angeles City, Philippines, as the son of a Voice of America foreign service officer. He attended junior high at the International School of Bangkok, and then transferred to Wagner High School on Clark Air Force Base in the Philippines.

After returning to America and graduating from the University of Miami in 1977, Matera worked as a reporter for The Miami News (1977–82). He covered the city beats—education, crime, politics and general assignment.

Matera became an independent author in 1986. His first mass market, non-fiction book, Are You Lonesome Tonight?, detailed the controversial story of Elvis Presley's lifelong relationship with a troubled Louisiana woman.

Matera has appeared in a half dozen television documentaries, including programs on The FBI's Top Ten Most Wanted, 1930s bank robber John Dillinger, 1960s cult leader Charles Manson, and 1970s giant serial killer Ed Kemper. Matera has also appeared in 9 episodes of the television show America: Fact vs Fiction which airs on the American Heroes channel.
