Sebaceans are humanoid aliens, in the TV Series Farscape, indistinguishable from humans in appearance. They have superior senses to humans and longer lifespans but are extremely sensitive to heat. Sebaceans lack a gland that regulates body temperature and under extreme heat conditions suffer delirium which rapidly degrades to a catatonic state they call the "Living Death," a fate they believe is worse than death.

Sebaceans make up the greater part of the Peacekeepers, a millitaristic mercenary organization that provides enforcement for planets without armed forces of their own. Sebaceans have settled many planets and all are not peacekeepers. Peackeepers are devoted to genetic purity and are opposed to the mixing of alien races.

In the miniseries Farscape: The Peacekeeper Wars, it is discovered that Sebaceans were humans taken from Earth many thousands of years ago by the Eidolons. They were brought to the Eidolon homeworld of Arnessk where their evolution was accelerated and they became aides to the Eidolons. When the Eidolons disappeared 12,000 cycles before Farscape began, The Peacekeepers carried on without them as best they could but they lacked the Eidolon's mediation abilities. As a result, they resorted to maintaining peace through threats and oppression.
