A galaxy is a system consisting of gases, stars, planets, and comets. Mario or Luigi visits many galaxies in their adventures through Super Mario Galaxy and Super Mario Galaxy 2. There is a total of 91 different galaxies between the two games: 42 in Super Mario Galaxy and 49 in Super Mario Galaxy 2.

The galaxies in Super Mario Galaxy are notably much smaller than real galaxies, often being composed of nothing more than a few small planetoids, most of which come in many different shapes and sizes. However, in Super Mario Galaxy 2, a galaxy proportionate to a real galaxy appears in the background of World 4, while in World 5, there is a galaxy supercluster. Smaller galaxies in the games are more comparable to systems such as the Solar System. There are solar systems that can be seen to make up other galaxies that determine whether it is a large or small one.

In Super Mario Galaxy, there is clearly a size difference between galaxies. Some of them contain six or seven Power Stars, while others possess only one (two in the Buoy Base Galaxy and the Gateway Galaxy). The "main" galaxies with six to seven Power Stars are usually much larger than the "bonus" galaxies with one Power Star, which may contain only one or two planetoids; there are 15 of these "main" galaxies and 27 "bonus" ones. In Super Mario Galaxy 2, however, this difference is not as prevalent, as each galaxy contains either two or three regular Power Stars; respectively, there are 25 and 24 of each.

In Super Mario Galaxy, most galaxies are observed from six different domes onboard the Comet Observatory. These domes show the player up to five galaxies and give them the option to fly to those galaxies in order to search for Power Stars. Just outside of each dome is a Hungry Luma, which transforms into an additional galaxy after the player feeds it a certain number of Star Bits. The remaining galaxies in the game are accessed via other areas on or around the Comet Observatory, including the Planet of Trials and the Gate. In Super Mario Galaxy 2, galaxies are grouped into seven different Worlds, each of which contains a total of seven galaxies. One Hungry Luma is encountered in each World, which transforms into a new galaxy when called to Starship Mario and fed the required number of Star Bits.

Many galaxies in both games contain black holes, which Mario and Luigi run the risk of getting sucked into if they fall off the edge of some planets or areas.

  • In both Super Mario Galaxy and Super Mario Galaxy 2, galaxies are commonly represented by three-dimensional revolving icons which consist of either one planet found in the galaxy or multiple planets in the galaxy. In Super Mario Galaxy, only 29 of the 42 total galaxies in the game have revolving icons, as the other thirteen remaining galaxies are accessed outside of one of the six main domes. In Super Mario Galaxy 2 however, every galaxy in the game has an icon. In addition, every galaxy icon in Super Mario Galaxy 2 is surrounded by a faint blue circular force field, possibly the atmosphere of the galaxy.
  • In Super Mario Galaxy, every object found on almost all of the revolving galaxy icons in the game remains stationary. In Super Mario Galaxy 2, however, almost every galaxy icon in the game has something moving on it. The reasons for this are unknown.
  • In Mario Kart 8 and Mario Kart 8 Deluxe, there is a sponsor named after Galaxies, Galaxy Air.
