A Third-Person View (3rd Person) is a camera angle which shows the player's body from behind, instead of looking as if through their eyes. This is in contrast to a First-Person View where the camera only sees the player's arms and weapon. Both views usually contain a HUD.
A 3rd-person view is available in all 3D GTA games - the 3D Universe and HD Universe. This excludes the top-down games in the 2D Universe, along with Grand Theft Auto Advance and Grand Theft Auto: Chinatown Wars. Chinatown Wars may have a more early style of game play, but it has a fully rotatable camera which is not present in any other Grand Theft Auto game.
