List of Andromeda races
- Avatars of Black Holes
- Avatars of Stars
- Avatar of the Abyss
- Bokor. Microscopic sentient parasites.
- Calderan: Featured in season 2 episode 5, "Last Call at the Broken Hammer," and episode 18, "The Fair Unknown"
Humans who lost their technology after crash landing on a new planet, and followed the path of Wayism taught by Theodore Blake, who had also taught Rev Bem in the past. Hajira are innocent and do not possess any secrets due to the ability to pass on their memories genetically to their offspring.
- Heavy Gravity Worlders. Humans genetically modified to withstand gravity much greater than Earth's; as the result, they are several times stronger than normal humans.
- Lambent Kith Nebula, a race of sentient suns. These suns interact with other races via avatars – for example, Trance Gemini is the living avatar of the sun Vedra, the oldest of the Lambent Kith Nebula. The suns of the Lambent Kith Nebula are the enemies of the Abyss, and aim to destroy it. When Trance discovers that rest of the suns in the Lambent Kith Nebula have come under the spell of the Abyss, she uses her own sun, traveling behind the Andromeda into the Route of Ages, to destroy the Abyss.
- Magog. Human-sized predators covered in a loose, shaggy pelt. They feed on sapient beings which they paralyse with toxin, and reproduce by laying their eggs in another living being: the larvae hatch and consume their host. The most significant Magog character in the series is Rev Bem, who eschews the "brutish violence" of the rest of the Magog. Their leader, or god, is the Spirit of the Abyss: the Magog say that he is their creator. Rev Bem says that the Divine created the Magog: "...the Divine also has nightmares, for he created us." 
- Nietzschean, a species of genetically engineered humans who follow the works of Friedrich Nietzsche, Social Darwinism and genetic competitiveness. They claim to be physically perfect and are distinguished from ordinary humans by bone blades protruding from their forearms. The race's Latin trinomial designation is Homo sapiens invictus, which means "undefeated thinking man" in English. They originated on planet Fountainhead, orbited by Ayn Rand station.
- Paradine. The Paradines are both referred to as evolved Vedrans, as well as the first race of sentient beings in the galaxy. Trance Gemini hypothesizes that the Paradines may have had a "hand in its [the universe's] creation". These problems are not expanded upon or resolved during the show's run. It is revealed, in the finale of season 4, that Dylan Hunt is half Paradine, from his father's side.
- Than-Thre-Kull. A sentient species: the Than are humanoid, in the sense that they have two arms ending in hands, and two legs; they are insectoid, in that their bodies are covered in a hard carapace, they have compound eyes and ant-like mandibles. Than are slightly smaller than humans on average, standing approximately 1.5 metres tall.
