I would say The Lord of the Rings trilogy, but I assume that you and every living, breathing creature out there has read it already because it is the best series on God's green Earth, ha ha.
Seriously though, Tolkien is, hands-down, my absolute favourite; basically, everyone else is competing for second-place. Also, don't stop at The Lord of the Rings. It's probably better to start out with The Hobbit, given that it's a prequel to the events in The Lord of the Rings. You'll also want to read Unfinished Tales and The Silmarillion, the latter being my favourite book ever (it is the epitome of his creative genius; a philosophical masterpiece that is the benchmark for all fantasy works thereafter).
As other people have pointed out, Nineteen Eighty-Four and Animal Farm are always great choices. As are Brave New World or Island by Aldous Huxley. Pretty much anything from the dystopian genre makes for a solid read, but maybe that's because I revel in messed-up societies and enjoy the fact that a book has the power to give me goosebumps or make my hair stand on end.
If you want to be depressed for the rest of your life, check out John Steinbeck for The Grapes of Wrath and Of Mice and Men. Ummm... anything by F. Scott Fitzgerald, C.S. Lewis, the Bronte sisters, Jane Austen, Fyodor Dostoyevsky, and Ray Bradbury (obviously there are more, but you get the idea).
