What would you say are the best Science Fiction Novels of all time?

Stranger in a Strange Land ~ Heinlein

Dune ~ Herbert

Time Enough for Love ~ Heinlein

The Sirens of Titan ~ Vonnegut

The Hitchhikers Guide to the Galaxy ~ Adams

A Wrinkle in Time ~ L'Engle

I've never been a big science fiction fan, but all of these were outstanding.

Foundation Saga

Android series

Starship Troopers

Dragon Riders Of Pern

Dune saga

Martian Chronicles

Out Of The Silent Planet

War Of The Worlds

The Time Machine

Flashforward

First Men On The Moon

Total Recall

Fantastic Voyage (ok, I know it was novelisation, but it was still bloody good)

The Postman

Micheal Crichton books (pure genius)

2001: A Space Odyssey

I Am Legend

Dorsai saga

Origin Of Species (if the Church had its way)

Red Mars by Kim Stanley Robinson

That book has great scientific REALISM. No FTL, no wormholes and teleportation. Arthur C. Clarke said it was great.

It is like most people have forgotten that science fiction has something to do with SCIENCE. Some books let this slide more than others but it is getting ridiculous. People are calling zombie stories science fiction.

The best sci-fi series is Lois Bujold's Vorkosigan series.

I love Orson Scott Card so Ender's Game.

Hitch Hiker's Guide to the Galaxy.

Philip José Farmer, Riverworld.

They just first come to mind, there must be many more, I haven't read anything for a fair while, not that I am really very well read.

"The tales of Alvin Maker" got me into reading novels.

You might simply check out the winners in the novel category for both the SFWA Nebula Awards and the Hugo Awards.

The criteria change over time, depending on who you ask, of course. Often cited historically speaking, are:

Alfred Bester's "Stars My Destination"

Frank Herbert's "Dune" series

The Martian Chronicles

the Foundation series

Etc.

I really like Ray Bradbury. and i guess there's the classics like War of the Worlds (never finished that one though. I read like the first chapter and got bored; it moves so slow! But I'll finish it one of these days.)

Anything written by Bradbury.

all sci-fi fans should be reading the destiny's children series by stephen baxter.
