The Black Order is a fictional supervillain team appearing in American comic books published by Marvel Comics. They are group of alien warriors with various supernatural abilities who serve Thanos. The original iteration consisted of Ebony Maw, Corvus Glaive, Proxima Midnight, Black Dwarf, and Supergiant.

The Black Order (barring Supergiant) appeared in the Marvel Cinematic Universe films Avengers: Infinity War (2018) and Avengers: Endgame (2019), where they were also known as the "Children of Thanos" and were made up of Thanos' adopted children.

The Black Order is a group of ruthless aliens that serve Thanos. They help Thanos raze worlds from which they demand tribute. When Corvus Glaive sent one of their Outriders to find a new world to raze, the Outrider targeted Earth.

The Black Order arrive on Earth in search of the Infinity Gems, which are under the control of the Illuminati. Each member of the Order targets a member of the Illuminati with varying degrees of success. During their search for the gems, Ebony Maw finds Thanos' son, Thane, whom Thanos wishes to kill.
