The 100 Most Popular Sci-Fi Books on Goodreads

Dystopias, alien invasions, regenerated dinosaurs, space operas, multiverses, and more, the realm of science fiction takes readers out of this world to tackle all-too-real issues, including oppression, bigotry, censorship, and the horrors of war. To celebrate the most inventive of genres, we’re exploring readers’ 100 most popular science fiction novels of all time on Goodreads.
As all good sci-fi readers know, the science behind the story is half the fun. To create our list, we ran the data to reveal the most reviewed books on our site. Additionally, each title needed at least a 3.5-star rating from your fellow readers to join this list. And, since science fiction is known for its continuing voyages, in the case of multiple titles from the same series, we chose the one with the most reviews.
Here are the top science fiction novels on Goodreads, listed from 1 to 100. We hope you discover a book or two you’ll want to read in this lineup, whether it’s a classic of the genre or one of the newer entries to sci-fi.

Thanks for mentioning Robert Silverberg. Agree.

Most disappointing omission author-wise would be Gene Wolfe.

I have read Binti and Kindred
I have others on my list...keep reading people and the list evolves and changes

Thought the same, then looked at her books on the site. Most of the Pern series is classified as 'Fantasy' even though anyone who has read them knows that they are Sci-Fi. She would've dominated this list if they had classified her books correctly.

I think you are looking at the wrong list, those are some great authors with great books but few in the sci-fi pile


Foundation should be #1 without a doubt, with Dune close behind. Haldeman higher too along with anything by Philip K Dick. Others could be added that are missing ..

Look at the criteria. They pulled the most reviewed books. Newer books have had less time to gain readers.


To those with different opinions, why not post your own? I'd love to read a bunch of different top 100s, or 10s, or 50s, or however many you'd like to list.

Obviously so many commenters failed to read this."
Exactly! Thank you!!

Quite a few still on my TBR list.


“COVID 1984” An Orwellian review on how to get an entire planet to conform to new social constructs without questioning what is really being hidden from them. Anyone like to read that??


48/100 for me. Interesting (and wonderful) that Tamsyn Muir made the list only a few months after her debut novel was published.


You could take out Asimov's Foundation. Great idea, but like all his fiction wooden characters. Otoh his non-fiction, explaining the solar system etc., is brilliant.


The Pratchett ones in this list are his worst work by a long shot thought?

The way the list is designed automatically favors older books - it is number of reviews, if average is 3.5+...

Stop shouting about things that are not important to the art of the writing.




Go take a chill pill!

I loved Left Hand of Darkness. Mainly because it was so different from anything I had ever read.

Mind-blowing."
I really like her stuff normally, but I've tried several times to read the left hand of darkness, and I can't manage to get through it. It's just too boring. Most of her stuff is great, the whole earthsea series, the gift, changing plains, and others, but I simply can't get through the let hand of darkness.



Aeon and Forge of God are my most favourite sci-fi reads."
Dittos. Nourse, Zelazny, Van Vogt..... many missing. Times change, the definition of "good" also. 🤔

You betcher bippy! Tunnel in the Sky, Star Surgeon, Have Space Suit, Will Travel. Ahh, a glorious misspent youth.😄


I totally agree! I would have also expected Claire North.

Obviously so many commenters failed to read this."
No, we're just surprised that's all! Luckily Commenters have this forum where we can express our disappointment and share our own favourite SF reads. Other lists exists.
Anne McCaffrey is fantasy, not science fiction. Different list."
Actually, she's both. She's written books about aliens and space. and the Pern series has a very scientific beginning. They're castaways on an alien world, regressing as they lose their technology. The dragons are adapted to fight the falling . . . and her Pegasus series, as well. Anne McCaffrey is very scifi.
