CNN Special Investigations Unit is an American investigative documentary program on CNN weekends.

Expanding upon "CNN Presents," SIU focuses on each episode being an investigative report about the news story being covered, commonly featuring a number of interviews with experts on the issue, in addition to possibly people who have witnessed the story taking place. The reports are commonly long-form, allowing for the network to cover more information and perspectives than would be available during a 5-minute report on another CNN program, such as "CNN Newsroom".

Compared to "Presents," the show has taken a slightly larger point of the reporting being done by CNN reporters, the first commercials promoting the program largely showing pictures of anchors and reporters on locations, asking questions to people on the locations. In addition, the look and feel of the show has changed somewhat drastically, adding more emphasis on the graphics used to present the program itself, in addition to the stories being covered.

Since the program's introduction, the network has slowly shifted towards relabeling past "Presents" presentations into "SIU" formatted ones, changing the graphics to reflect the new general label given to long-form reporting done by the network.

"CNN: Special Investigations Unit" taps into the network's worldwide resources and deep bench of top-notch journalists, including chief international correspondent Christiane Amanpour, anchors Anderson Cooper, John Roberts, and Soledad O'Brien, chief medical correspondent Dr. Sanjay Gupta, correspondents John King, Candy Crowley, Abbie Boudreau, Drew Griffin and others to offer a strong brand of enterprise investigative reports.
