The broadcaster announced that it has secured the free-to-air rights to the first two seasons of the show.
The drama is based on the Danish series Forbrydelsen, which became a cult hit when it aired on BBC Four earlier this year.
It focuses on the investigation into the murder of a young girl in Seattle and examines the impact of the case on the victim's family and the town's political figures.
The cast includes Big Love's Mireille Enos, Billy Campbell, True Blood's MIchelle Forbes, Brent Sexton and Joel Kinnaman.
Channel 4's chief creative officer Jay Hunt said: "We are thrilled to acquire The Killing. This intense, atmospheric crime thriller redefines the genre and will sit perfectly alongside Channel 4's stable of award-winning, critically acclaimed US shows."
The first season of The Killing is expected to air in the UK later this year.
