The name Liberty City can refer to three cities:
All three Liberty Cities mentioned above are fictional cities on the Eastcoast of North America, based on New York. Liberty City is the most frequently used city in the Grand Theft Auto series. Five of the eleven GTA's are set in this city, and Liberty City has an important role in several other GTA's.
Because Liberty City appears in three era's of GTA, there are three completely different versions of the city.
