Day of the Departed is a television special of the computer-animated television series Ninjago: Masters of Spinjitzu (titled Ninjago from the eleventh season onward). The series was created by Michael Hegner and Tommy Andreasen. The special aired on 29 October 2016 to coincide with Halloween and follows the sixth season titled Skybound. It is succeeded by the seventh season, titled Hands of Time.

The 45-minute halloween special replaced the release of a second season for 2016, due to the ongoing development of The Lego Ninjago Movie, which was released in 2017. The special focuses on the events of the Day of the Departed, a national holiday celebrated in Ninjago in which loved ones are remembered. The storyline focuses on the ninja character Cole, who becomes concerned about fading away in his ghostly form, and his battle with the main antagonist Sensei Yang. While Cole is trapped in Yang's temple, the ninja must battle several villainous spirits that he has accidentally released.
