Books

1. Aldous Huxley's Brave New World. It's a must read if you're into dystopia. Unlike Orwell, Huxley doesn't focus on politics of his time. Specially good to read alongside Island, an utopia of the same author, dealing with similar topics (society, drugs, the human condition).
2. Anthony Burgess' A Clockwork Orange. It has some satirical vibes, but it is not a good book to read if you're feeling down (content warning: sexual violence). It focuses on a teen gang leader in the near future, and talks about themes like the impact of free will on morality.
3. William Golding' Lord of the Flies. Technically not a dystopia, but it "scratches" the same itch. It's about a bunch of kids dumped in an island, without adult supervision, and the resulting nasty proto-society that they build from it.
4. Yevgeny Zamyatin's We. It's perhaps one of the grandparents of the genre; it talks about individuality on a society controlled by a state that managed to conquer the whole globe.

There's also Ayn Rand's Atlas Shrugged. I don't recommend it - the book is basically a "if Orwell was right-wing, soapboxing instead of trying to explain what's going on, and with poor writing skills". Seriously.

The Stand by Stephen King

The Handmaid’s Tale

Brave New World (kind of dystopian…)

Fahrenheit 451

I found "A Canticle for Leibowitz" an astounding read. More apocalyptic than dystopian, but solid.

The Road, by Cormac McCarthy. Very grim, but beautifully written.

I think Le Guins "The Dispossessed" belongs here. Its a dystopian/ utopian comparative about an anarchist planet and a capitalist planet. Highly recommend. I've got a signed copy somewhere.

Fahrenheit 451! It's a pleasure to burn!

I have not quite finished the book yet, but Kim Stanley Robinson's The Ministry for the Future is hard-science fiction set in the near future when climate change tipping points start to be reached, and it is so far my favorite book in a long time. It is dystopian, but not bleak or hopeless.

Checkout Wool by Hugh Howey. The Silo TV series is based on it, great story!

William Gibson's Sprawl series. Neuromancer, Count Zero, and Mona Lisa Overdrive.

Jennifer Government by Maxx Barry. In fairness I read it 20 years ago and do not know how it's aged. It was good back then though.

The MaddAddam Series by Margaret Atwood.

1. Oryx and Crake
2. The year of the flood
3. Maddaddam

*Neuromancer by William gibson is crazy dark and is the book which started the cyberpunk genre.

The forever war by Joe Hadleman is cynical but not totally dark, still has some awesome dystopic themes which have not lost their power over he years. Hard to say if it could be read as critical of current gender ideology or in support of it.

If you've ever thought about getting into the 40k universe Dan Abnett is great and his writing of female characters gets better over the years.

Alastair Reynolds and peter f Hamilton mention many societies in their space operas and generally have a pretty grim, imo realistic, view of human nature and how it might follow us to the stars.

Brave new world is an interesting concept for those who like dyspotic worlds. IMHO not a great book, still worth a read.

Metro 2035

I get plenty of dystopian stuff in the news - I advise reading something to escape reality.

This is almost the opposite of a dystopia, but I think still fits.

The Dispossessed by Ursula K. Le Guin - A character from a utopia returns to dystopian earth. It's primarily the main character wandering around realizing how terrible things could get on our current trajectory. It's great!

Wool

Three good novels to see if you have a taste for cyberpunk: The Diamond Age: Or, a Young Lady's Illustrated Primer and Snow Crash by Neal Stephenson, and Neuromancer by William Gibson. The first is lush and leisurely, the latter two are very lean and fast-paced.

As a slightly different take I'd recommend SS-GB. Technically it's an alternative history novel whether the Nazis won WWII and conquered the UK.... But that's pretty dystopian in practice, especially when the main character is a policeman.

I don't know if The Trial counts exactly as a dystopia but it certainly conjures up the paranoia and confusion of being caught up in a beruacratic nightmare like you might find in a police state.

High Rise is a great satire on the class system translated to people moving into the then new high rise blocks in the UK - only the rich can afford the apartments at the top and so on. The first sentence involves the hero having to eat a dog to survive.

A Clockwork Orange has been mentioned already, but it's easily my favourite. And very different and more brutal than the film, which is also great but more its own thing. Alex is a much nastier piece of work in the book, and the last chapter of the novel isn't in the film

There is a list on wikipedia:

List of dystopian literature

Random Acts of Senseless Violence was a good read.

'Walt To The End Of The World' Suzy McKee Charnas. Centuries after the nuclear war, women are treated as slave/chattel because they caused the War. imho much better than 'Handmaid's Tale.'

Metroplis by Thea Von Harbeau.

Bonus if you can get the illustrated edition by Michael Kaluta:
