"Zuma Canyon" is the ninth episode of the revamped and renamed Law & Order spinoff, Law & Order: LA. The episode originally aired on April 11, 2011 on NBC.

Law & Order: LA, originally titled Law & Order: Los Angeles, is an American police procedural and legal drama television series set in Los Angeles, where it was produced. Created and produced by Dick Wolf and developed by Blake Masters, it premiered on NBC on September 29, 2010, as the fifth series in Wolf's Law & Order franchise. Law & Order: LA debuted after the original Law & Order ended its 20-year run the previous spring. The show received a full-season pickup on October 18, 2010. On January 18, 2011, however, NBC announced that it was putting the series on hold indefinitely. According to a representative of the show, the scheduling change was not caused entirely by the mid-season cast shake-up. The network later announced a return date for the series, April 11, 2011; and the final episode scheduled for July 11, 2011. On May 13, 2011, NBC canceled the series after one season.
