Evan Hunter (born Salvatore Albert Lombino; October 15, 1926 – July 6, 2005) was an American author of crime and mystery fiction. He is best known as the author of the 87th Precinct novels, published under the pen name Ed McBain, which are considered staples of the police procedural genre.

His other notable works include The Blackboard Jungle, a semi-autobiographical novel about life in a troubled inner-city school, which was adapted into a hit 1955 film of the same name. He also wrote the screenplay for Alfred Hitchcock’s 1963 film The Birds, based on the Daphne du Maurier short story.

Lombino published a handful of short stories under his birth name before adopting Evan Hunter in 1952 as both his legal name and the name he used for general fiction. He initially used Richard Marsten for genre fiction, but this fell by the wayside after the 87th Precinct series was launched under the name of Ed McBain. He also published one novel each as John Abbott, Curt Cannon and Ezra Hannon, and two novels as Hunt Collins. Most of the books he wrote as Marsten and under miscellaneous pseudonyms were later reissued as the work of Ed McBain.

Salvatore Lombino was born and raised in New York City. He lived in East Harlem until age 12, when his family moved to the Bronx. He attended Olinville Junior High School (later Richard R. Green Middle School #113), then Evander Childs High School (now Evander Childs Educational Campus), before winning a New York Art Students League scholarship. Later, he was admitted as an art student at Cooper Union. Lombino served in the United States Navy during World War II and wrote several short stories while serving aboard a destroyer in the Pacific. However, none of these stories was published until after he had established himself as an author in the 1950s.

After the war, Lombino returned to New York and attended Hunter College, where he majored in English and psychology, with minors in dramatics and education, and graduated Phi Beta Kappa in 1950. He published a weekly column in the Hunter College newspaper as "S. A. Lombino". In 1981, Lombino was inducted into the Hunter College Hall of Fame, where he was honored for outstanding professional achievement.

While looking to start a career as a writer, Lombino took a variety of jobs, including 17 days as a teacher at Bronx Vocational High School in September 1950. This experience would later form the basis for his novel The Blackboard Jungle (1954), written under the pen name Evan Hunter, which was adapted into the film Blackboard Jungle (1955).

In 1951, Lombino took a job as an executive editor for the Scott Meredith Literary Agency, working with authors such as Poul Anderson, Arthur C. Clarke, Lester del Rey, Richard S. Prather, and P. G. Wodehouse. He made his first professional short story sale the same year, a science-fiction tale titled "Welcome, Martians!", credited to S. A. Lombino.

Soon after his initial sale, Lombino sold stories under the pen names Evan Hunter and Hunt Collins. The name Evan Hunter is generally believed to have been derived from two schools he attended, Evander Childs High School and Hunter College, although the author himself would never confirm that. (He did confirm that Hunt Collins was derived from Hunter College.) Lombino legally changed his name to Evan Hunter in May 1952, after an editor told him that a novel he wrote would sell more copies if credited to Evan Hunter than to S. A. Lombino. Thereafter, he used the name Evan Hunter both personally and professionally.
