CSI: NY is an American police procedural television series, which premiered on September 22, 2004. The series was the second spin-off, indirectly, from the popular CBS show, CSI: Crime Scene Investigation, and directly from CSI: Miami, during an episode of which several of the CSI:NY characters made their first appearance. What sets CSI:NY apart from the others in the franchise is the focus on character development, which creators believed could be done without undermining the core, procedural aspects of the show.

CSI: NY is produced in partnership with the Canadian media company Alliance Atlantis. The show was renewed for a fourth season, which premiered on Wednesday September 26, 2007.

Due to the writers strike ending, CBS has announced that the show will return on April 2, 2008, with seven episodes.

Andy Garcia (I) was originally offered the lead role, a character who would have been named Det. Rick Calucci. He declined the role, as did Ray Liotta.

Anthony E. Zuiker wanted The Who's "Behind Blue Eyes" ("Blue" being a figurative term for a police officer) to be the show's theme song. However, CBS president Leslie Moonves turned it down in favour of "Baba O'Riley" (also by The Who).

Stella's name was derived from Stella Kowalski from Streetcar Named Desire, A (1951) and Salvatore Corsitto's character Amerigo Bonasera from Godfather, The (1972).

The only one of the C.S.I. shows to not win an Emmy.

Danny Messer claims that he had a short-lived career in the music business, and that he quit baseball when he broke his wrist in a fight.

While filming on location in downtown Los Angeles, an actual dead body was found in an apartment building, several floors down from the film crew's location. The body turned out to be the mummified remains of a long-dead tenant. The main cast was not on set at the time. In an ironic twist, one of the cases in episode 302, "Not What It Looks Like," involves a missing woman whose mummified body is found in an abandoned apartment.
