Makai Senki Disgaea (魔界戦記ディスガイア, Makai Senki Disugaia, "Netherworld Battle Chronicle Disgaea") is an anime series based on the video game Disgaea: Hour of Darkness. Makai Senki Disgaea follows the same general plot as the game, but with several alterations to characters and chronology. The anime was licensed by Geneon Entertainment before they closed their doors in 2007. On September 1, 2010, North American anime distributor Funimation announced that they had rescued the series, and they released the complete series in 2011.

A bonus feature on the DVD of Disgaea 2: Cursed Memories was a trailer of what the Disgaea anime would look like. However, the anime turned out to be completely different from what was shown in the trailer. No explanation was given for the drastic departure of the final anime from the trailer. A preview of the Disgaea anime was also available on another Geneon anime DVD, Hellsing Ultimate OVA I.

Makai Senki Disgaea is also the title of several distinct manga and light novel series based on the Disgaea game series.
