All links checked and updated on December 25th, 2015, if you have an older version please contact customer service. To download free eBooks directly, you must use Kindle Fire. Amazon has changed their other Kindle reader software (PaperWhite, eInk and Touch) so those users must use this eBook in Amazon's downloadable Cloud Reader (read.amazon.com) on a PC or laptop to select and send the free classics to their Kindle. iPad users must use the Cloud Reader from "Manage Your Kindle" to use the download links, see "From The Author" below. Amazon Prime members are welcome to use their free monthly borrow to get this list and download hundreds of the free classics for future reading.

This linked list of over 350 free science fiction stories and novels in Amazon's permanent collection was recently updated with hundreds of works from famous science fiction writers who wrote in the 1950's and 1960's and apparently forgot to extend their copyright protection. For the more recent authors SciFi fans will be familiar with, I just list the links (arranged by author) that will take you to their titles in the Kindle store for free download. For the earlier writers, I usually include a one or two line summary of their books.

I thought I read all the classic SciFi twenty years ago, but I found a couple dozen authors I'd never heard of while researching Amazon's free collection. Most of the titles in this linked list of the free classic science fiction on Amazon were written before the "Golden Age" of science fiction, but influenced the authors who came later. I've included several early utopia/dystopia books, a popular subject in the late Victorian period. A few supernatural titles are included when the author also wrote other types of books. I didn't include fairy tales, and I made judgment calls on skipping science fiction/fantasy that was written for children and young adults, or just included a few samples from those authors.

This list of free science fiction eBooks on Amazon works best on Kindle WiFi devices, and Fire. The newest 3G and 4G Kindle Paperwhite and Touch readers will only allow you to use the clickable links for free Amazon eBooks when you are using them on a WiFi network. Clicking the linked titles will bring you directly to the product page for the free eBook in the Kindle store, where you can sign into your Amazon account (required the first time only) and download the eBook immediately.

If you are reading on an old Kindle 2 or Kindle 1, you can add the book to your Wish List and the next time you use a computer to access Amazon, you can have the Wish List items sent to your Kindle for free.

Amazon Prime members can use their free monthly borrow to get this list and download all of the free books for later reading.
