NBC has renewed the two series, but spin-off Law & Order: Organized Crime is in a slightly more precarious position.
The network has renewed Law & Order for season 24, while Law & Order: Special Victims Unit will return for season 26.
The future of Law & Order: Organized Crime, which is in its fourth season, is still up for debate at the network. Law & Order: Organized Crime is the lowest rated of all of Dick Wolf's NBC series and has had several showrunners over time.
Matt Olmstead started as showrunner and was replaced by Ilene Chaiken, who was replaced by Barry O'Brien. Bryan Goluboff was named showrunner for season three, but left after three months and was replaced by Sean Jablonski, who also left shortly after due to 'creative differences' and was replaced by David Graziano. John Shiban is the showrunner for season four.
The changes come as NBC also renewed One Chicago trio Chicago Med, Chicago Fire and Chicago PD.
Law & Order itself has undergone some significant casting changes. Jeffrey Donovan, who played Detective Frank Cosgrove, left before the production and Veep actor Reid Scott joined the cast as Detective Vincent Riley.
Then, after almost thirty years and more than 400 episodes, it turned out that Sam Waterson, who played Jack McCoy, was leaving the series. Scandal actor Tony Goldwyn joined as the new district attorney, Nicholas Baxter.
Mehcad Brooks, Camryn Manheim, Hugh Dancy and Odelya Halevi also star.
Law & Order is averaging 7.7 million viewers, up 56% and 122% in the demo, according to NBC.
Law & Order: Special Victims Unit revealed earlier this month that Kelli Giddish would return as Amanda Rollins. The series is led by Mariska Hargitay, who is expected to return for season 26. Ice-T, Peter Scanavino and Octavio Pisano also star.
According to NBC, Law & Order: Special Victims Unit is averaging 11.2 million viewers, up 111% and up +325% in the demo. David Graziano is the showrunner.
All series are produced by Universal Television, in association with Wolf Entertainment.
