No as of this moment in time there are only 3 movies that exist in the Marvel Movie Cinematic universe. Iron Man 1 and 2 and The Incredible Hulk. Every other Marvel movie isn't a part of that.
Anything with the Marvel Studios logo on it, is part of the same continuity. Everything that doesn't, even if it's a Marvel comic book adaptation, is not.
Every movie except from the 3 I've mentioned were all produced by various different picture houses and thus are not part of that same "cinematic" continuity.
That's why it's a good thing Marvel want to reboot Spider-man and X-Men cause it'll bring them into that same cinematic continuity.
