AMC initially cancelled the crime drama in July 2012, but reports suggested in December that the network would order a third season as a co-promotion with Netflix.
Charlie Collier - AMC's president - announced on Tuesday (January 15) that The Killing will air 12 new episodes on the cable channel, although there was no mention of a deal with Netflix.
Mireille Enos and Joel Kinnaman will be back for season three, but stars of the first two seasons Billy Campbell and Michelle Forbes will not be back.
The Killing's third season will be set a year after season two and see Sarah Linden (Enos) return to detective work to help former partner Stephen Holder (Kinnaman) solve a new case.
Veena Sud, the series' showrunner, said of the renewal: "I couldn't be happier to know that I will be returning to work with AMC, FTVS and Mireille and Joel on what is and has always been a passion project for me.
"To the fans that have supported the series, thank you for doing so. My team and I will work hard to deliver the best story that we can for season three."
The Killing is based on the critically-acclaimed Danish series Forbrydelsen, which aired from 2007 to 2012.
AMC is expected to broadcast The Killing's third season later this year.
