King Arthur

Malory, other medieval romances for shits & giggles I suppose
T.H. Whites The Once and Future King
Marion Zimmer Bradleys The Mists of Avalon

Bonus stuff that draws on it:
Tim Powers The Drawing of the Dark
Robert Holdstocks Mythago Wood
Gene Wolfes Wizard Knight

All tv and film depictions of Arthur are utter shit as far as I have ever since, and it seems to be getting worse.
John Boormans Excalibur almost achieves depicting the mythical conception but has a lot of unintentional cheese

Yeah, that's probably the most comprehensive and foundational thing you can read on Arthurian legend. Sadly, I found it to be incredibly dry and uninteresting for the most part. Don't mean to discourage you, just warning you that you may not like it. Also, it's very long, so it will be a pain to finish it if it isn't engaging you. Try it out, and if it's a struggle, just find a shorter secondary Arthurian legend primer or something.

Also, another book influenced by it that the above anon didn't mention: A Connecticut Yankee in King Arthur's Court - Mark Twain.

That's a satire

I'd also add a 'preceding material' such as the Fisher King and Tristan & Isulte - older works incorporated into the myth, especially the wounded king and withered land and its rebirth from the Fisher King play into Arthur

Mabinogion too
Original and Evangeline Waltons interpretation

Thank you everyone!
