List of Law & Order: Criminal Intent episodes

Law & Order: Criminal Intent is an American police procedural television series set and filmed in New York City. It is the second spin-off of the long-running crime drama Law & Order. Law & Order: Criminal Intent follows a distinct division of the New York City Police Department: the Major Case Squad, which investigates high-profile murder cases, such as those involving VIPs, local government officials and employees, the financial industry, and the art world. Unlike the other series in the Law & Order franchise, Law & Order: Criminal Intent gives significant attention to the actions and motives of the criminals, rather than primarily focusing on the police investigation and trial prosecution. Episodes do not usually contain trials, and often end in confessions rather than plea bargains or verdicts.

Law & Order: Criminal Intent premiered on NBC on September 30, 2001. Following a ratings decline, the series moved to the USA Network after the end of its sixth season. CI continued with its seventh season on USA Network on October 4, 2007, and ended at its tenth season on June 26, 2011.

During its ten-season run on the two networks, 195 original episodes were broadcast.
