This article provides a list of fictional planets featured in Stargate SG-1 and Stargate Atlantis.
See also: Humans in SG-1, Humans in Atlantis
In the Stargate fictional universe, with the use of the Stargate device, and much later in the series, with the advent of a small number of space-faring vessels, humans of Earth have come into contact with a large number of other Earth-like, populated planets. Whilst most planets are shown only once, and then revisited periodically in the background of the show, some planets become key locations in the plot. Examples include the planet Abydos, the original planet visited in the Stargate movie; Chulak, Teal'c's homeworld; Dakara, the centre of the newly-formed Free Jaffa Nation; and Langara, homeworld of Jonas Quinn.

Some critics of the show point to the implausibility that 99% of planets encountered are habitable to humans, and are ultimately very similar to Earth. This is in fact an oversight: the Stargates were not scattered randomly, but rather were placed selectively on planets like Earth; thus planets like Earth are the only destinations reachable. In addition, the use of MALPs means that episodes simply do not occur on non-Earthlike planets. Likewise, the reason that most planets are inhabited by humans is that the Stargates were used predominantly by the Goa'uld for carting humans from Earth to other planets as slaves. Further, it has been stated that the Goa'uld terraformed many new planets over thousands of years to be more habitable for their human slaves.

Some of the planets listed were taken from the cartouche on Abydos, as this was originally the only planet that could be dialled from the earth stargate. However, after visiting the cartouche, the SGC were able to make the correct calculations compensating stellar drift.

The list of planets is separated by the galaxies in which planets are found, as travel tends to be restricted to within one galaxy - the Milky Way in SG-1, and the Pegasus Galaxy in Atlantis. Where available, the Stargate address and SGC designation are included.

Most Stargate-accessible locations are assigned an SGC designation of the form P0X-000 (M0X-000 is used for moons), where "0" is replaced by a letter or number. "It's based on a binary code the computer uses for extrapolation", according to Samantha Carter ("The Broca Divide"). Dr. Jackson and Lt. Ford ("The Siege (Part 1)") have suggested easier-to-remember nomenclatures without success. However, if the local name of a planet is known then that name is often used in place of the designation.

When dialling a gate, it is important that (within the Milky Way, for the most part) a seventh chevron be encoded - for the point of origin. There are instances where eight chevrons are required - such as dialing distant galaxies, such as Ida (the home of the Asgard) or Pegasus, the location of Atlantis. Additionally, a ninth chevron exists on the Stargate, though its purpose is not yet known.
