Darker than Black is a 2007 supernatural Japanese anime series created by Tensai Okamura. Ten years prior to the events of Darker than Black, a mysterious spatial anomaly known as "Heaven's Gate" appeared in South America, shortly followed by the opening of "Hell's Gate" in Tokyo altering the sky and wreaking havoc on the landscape. During this time, people possessing various special abilities emerged, each capable of different supernatural feats—these are known as Contractors. The series follows the exploits of agents Hei and his comrades of the Syndicate organization operating in a post-apocalyptic Tokyo and their mission to uncover the mysteries of the Hell's Gate.

The 25-episode anime was produced by Bones. It was directed and written by Tensai Okamura, along with character designs drawn by Takahiro Komori and based on the original designs by Yuji Iwahara, art direction by Takashi Aoi, sound direction by Kazuhiro Wakabayashi and soundtrack music composed by Yoko Kanno. The series premiered on MBS between April 5, 2007 and September 27, 2007 and aired later on HBC, CBC, TBS and Animax.

Aniplex released the complete series in Japan on nine DVD volumes between July 25, 2007 and March 26, 2008. The ninth DVD volume also included an unaired 26th original video animation episode. Aniplex later compiled the series in a Blu-ray box set released in Japan on September 30, 2009. The series was also licensed by Funimation for an English release in Region 1. Funimation released the series in six DVD volumes between November 25, 2008 and August 11, 2009. Funimation later released the series in a DVD box set on April 19, 2011 in Region 1.
