Law & Order is a media franchise composed of a number of related American television series created by Dick Wolf and produced by Wolf Entertainment. They were originally broadcast on NBC, and all of them deal with some aspect of the criminal justice system. Together, the original series, its various spin-offs, the TV film, and crossover episodes from other shows constitute over 1,000 hours of programming.

Shared characters and fictional organizations, such as Hudson University and the New York Ledger tabloid newspaper, serve as connecting links between the shows. Many supporting characters, such as district attorneys, psychologists, and medical examiners are also shared among the shows. Occasionally, crossovers of main characters or shared storylines between two of the shows will occur. A few major characters have also left the cast of one show within the franchise only to eventually join another. The music, style, and credits of the shows tend to be similar, with the voice-over in the opening of every series performed by Steven Zirnkilton."Ask the Editors"; TV Guide; April 19, 2010; Page 6. The shows share the iconic "dun, dun" sound effect of a jail cell locking, created, along with the theme songs, by Mike Post. Past episodes of the American series are in syndication with local over-the-air stations, along with cable channels such as USA Network and Bravo (both owned by the franchise's production company, NBCUniversal), Warner Bros Discovery's TNT, WGN America, E. W. Scripps Company's network Ion Television, and AMC Networks' SundanceTV and WeTV, showing episodes sometimes up to six times a day. Its ubiquity on the NBCUniversal fledgling streaming platform Peacock ("...19 zillion reruns...") was noted by The Wall Street Journal in January 2024.

In October 2012, Law & Order: Special Victims Unit showrunner/executive producer Warren Leight said of the future of the Law & Order franchise, "[Dick Wolf and I] sometimes talk in general terms of where (the franchise) could go. I'm curious to see if there's another iteration somewhere down the line", before adding: "We try hard to maintain a certain level of quality which I think is why the shows sustained in reruns so well. And I'd like to believe there's room for another generation in some way." In February 2015, NBC was purported to have interest in bringing back the flagship Law & Order as a limited series. On September 28, 2021, NBC announced that a 21st season had been ordered.

In development/unproduced series

Law & Order: Hate Crimes In September 2018, NBC announced that it had given an order of 13 episodes for a new installment of the franchise, titled Law & Order: Hate Crimes, which would be introduced on Law & Order: SVU. Later, on March 4, 2019, NBC said that the series would be heading back into redevelopment to flesh out the concept and such an introduction on SVU would not take place. The series was once again touted in 2020 as part of a multi-year contract signed with creator Dick Wolf. The series would likely move to Peacock due to language concerns as of June 2020.

Law & Order: For the Defense NBC had given a straight-to-series order to Law & Order: For the Defense on May 3, 2021, a new legal drama from creator Wolf that would take a look inside a criminal defense firm. The premise of the ordered series was to put defense attorneys under the microscope, along with the criminal justice system, with every week delivering the promise of a contemporary morality tale. On May 14, NBC announced that the series would premiere during the 2021–22 television season, leading off a trio of Law & Order franchise series on Thursdays in the same manner as the network's Wednesday Chicago grouping. On July 15, multiple trade publications reported that NBC and Wolf had mutually agreed to scrap the series, which had not yet cast any roles, and that a different Law & Order–related program, later revealed as the revival of the original series, was in the works.
