Races and species in The Hitchhiker's Guide to the Galaxy

This is a list of races, fauna, and flora (as well as creatures without category) featured in various incarnations of The Hitchhiker's Guide to the Galaxy. The fictional creations have, as they are comedic, real-world parallels.

These are the intelligent races as described by author Douglas Adams in his "Hitchhiker's Guide to the Galaxy" series of novels.

The popular anti-teleport song claims that "Aldebaran's great, Okay", but the Aldebarans are better known for their liqueurs (sold at Milliways), and fine wines (as Trillian prepared for Zaphod after deactivating all the Heart of Gold kitchen synthomatics).

It will take less than thirty Altairan dollars a day for hitchhikers to see the universe; so long as said hitchhikers avoid buying fruit drinks at Ursa Minor Beta bars, which cost sixty Altairian dollars. Zaphod Beeblebox mysteriously receives an annual 60,000 Altairian dollars into his Brantisvogan account; however, the currency is also said to have "recently collapsed". Ford Prefect says wistfully, "if I had one Altairan dollar for every time...".

The Amoeboid Zingatularians appear as a stellar replacement in the long-running comedic play No Sex Please, We're British at the end of Fit the Third of the radio series.

Inhabitants of the planet Bartledann. The people of Bartledann are similar to humans, but do not breathe. Due to their view on the Universe – that the Universe is what the Universe is, take it or leave it – they have no desires, dreams or hopes, to the point that the protagonist of a large boring book abruptly dies of thirst in the penultimate chapter of the book due to a briefly mentioned plumbing problem earlier on. Bartledannian literature is renowned, and its books are notable for being exactly one hundred thousand words long. Netball is a popular sport among the people of Bartledann despite the fact that no one cares about winning. Arthur meets them in Mostly Harmless during his search for a new home.
