CSI: Miami is a spin-off of the CBS network series CSI: Crime Scene Investigation. The series is an American crime drama television series that trails the investigations of a team of Miami-Dade forensic scientists as they unveil the circumstances behind mysterious and unusual deaths and other crimes. The pilot episode was first broadcast on May 9, 2002 as an episode of CSI: Crime Scene Investigation and six seasons have been aired. CSI: Miami currently airs on Mondays, at 10:00 p.m. on CBS. The series is produced in partnership with the Canadian media company Alliance Atlantis and CBS Paramount Television.

CSI: Miami is the only show in the CSI franchise to have crossed over with both CSI: Crime Scene Investigation and CSI: NY, but is the only one out of the three who has yet to crossover with a series outside of the franchise. CSI: Miami has also crossed over CSI: NY on more than one occasion.

The show has been heavily criticized—almost since its debut—by police and district attorneys, who feel CSI: Miami portrays an inaccurate image of how police solve crimes, and by the Parents Television Council, who note the level and gratuitousness of graphic violence, images and sexual content seen on the show. Nevertheless, in 2006 the show was reported as being the most-watched television show in the world.
