A couple that spring to mind:

Kafka is probably on my list too - not just The Trial, but several of his short stories too; Metamorphosis and In the Penal Colony, for instance. I'll never understand people who think Kafka is depressing; well OK, he is, but he's side-splittingly funny as well. In his own way.

The Master and Margarita by Michail Bulgakov, most definitely. I must have read it three times at least by now. One of the best satires I've ever come across, plus it manages to not only complain but stand for something as well.

Crime and Punishment. Clichéd perhaps, but it was the first Dostoevsky I ever read, it's one I keep coming back to and keep comparing other novels to - and I don't even really agree with it! But it's such a masterful look at what makes a human being that I can't get away from it. Plus I love how Dostoevsky managed to write a book that works on several levels - the first time I read it I read it like a detective story, and it works perfectly like that. With every re-read I keep finding new levels in it.

The Hitch-Hiker's Guide To The Galaxy. What can I say? I think I've read it 7 or 8 times at least, and now that I've finally gotten hold of Douglas Adams' own reading of it I'm going to listen to the audiobook this summer. It's just pure, undiluted fun.
