The following is a list of missions featured in Grand Theft Auto IV. For a list of missions in The Lost and Damned and The Ballad of Gay Tony, see Missions in The Lost and Damned and Missions in The Ballad of Gay Tony. In the game, many missions are available at the same time from multiple characters, so this list does not reflect any required chronological order of completion. Each character's respective missions, however, can only be completed in the order listed. And, of course, some characters and their respective missions may not be unlocked until certain missions are completed. The list is done in a logical order in which it can lock chronologically with The Lost and Damned and The Ballad of Gay Tony.
