The relationship between Gil Grissom and Sara Sidle is one of the oldest on CSI: Crime Scene Investigation.

The relationship was nicknamed GSR by fans, short for "Grissom Sara Romance". This is a pun on the CSI abbreviation, "Gun Shot Residue". In a May 25, 2006 interview with the Chicago Tribune, the show's executive producer Carol Mendelsohn indicated that the relationship between Grissom and Sara is "not so new" and they have been a couple for some time.
