Goldblum will replace Chris Noth, whose character Mike Logan is leaving the crime series after three seasons.
"Jeff's presence will add a new dimension to an already successful show," said Law & Order boss Dick Wolf.
Discussing Noth's departure, Wolf said: "Chris has been a member of the Law & Order family since the beginning, and Mike Logan is one of the most popular detectives in the history of television. We all wish him the best."
Noth appeared in the original Law & Order series from 1990 to 1995, then reprised his role in the Criminal Intent spinoff a decade later.
Goldblum and Vincent D'Onofrio are to split starring duties in the upcoming eighth season of Law & Order: CI.
