An alien species created for the military science-fiction series Stargate SG-1. The Goa'uld are a worm-like, parasitic species who tend towards interplanetary domination. A minority faction of the Goa'uld species, called the Tok'ra, oppose this culture.

The Goa'uld species is, as previously noted, parasitic, and requires a host body to survive. While Goa'uld initially took members of the Unas species, a species that developed on the same planet, in more recent times they take predominately human hosts. To distinguish them from the host, Goa'uld are sometimes referred to as "symbiotes".

Goa'uld have a natural healing ability that grants them very long lives and the ability to recover from many injuries, although damage to their host is often more easily repaired than damage to the symbiote itself.

The Goa'uld species has divided into two factions:

The Goa'uld
Members of the larger faction, who refer to themselves as "Goa'uld", tend towards megalomania and interplanetary domination. They impersonate religious figures to inspire a slavish devotion among their technologically-primitive subjects, and enforce their godly reputations with advanced technology.

Most Goa'uld who have appeared on the show have borrowed from Ancient Egyptian mythology, but not all. Other cultures that have been co-opted by the Goa'uld include the ancient Chinese and Japanese, Canaanite, Judeo-Christianity, and African aboriginal cultures.

The Tok'ra The Tok'ra are a minority faction among the Goa'uld species who oppose the Goa'uld faction's desire for galactic domination. Philosophically opposed to their Goa'uld kin, they reject the name and have a more symbiotic relationship with their hosts.
