- "If you are arriving by plane, your first steps on Liberty City turf will probably be in Dukes. Francis International Airport sprawls across the eastern tip of the borough and serves as an international hub for the rest of the country. Dukes should be experienced first-hand rather than from a cab window as you race to catch your flight home. One of the newer attractions is the National Union of Contemporary Arts (NUCA), a museum of modern art crammed full of canvases with ... To the east of NUCA lies Meadows Park where you will find relics like the Monoglobe and Liberty State Pavilion Tower leftover from a world fair half a century ago. If you are comfortable with drunken men throwing lethal weapons around a crowded bar, finish your day with a game of darts at the famous Steinway Beer Garden."
- ―Liberty City area street map description
Dukes is a borough of Liberty City in Grand Theft Auto IV. While it only contains nine out of the city's sixty five neighborhoods, the Dukes neighborhoods themselves are large, thus the borough is large, being slightly larger than its neighboring borough Broker, thus becoming the second largest after Algonquin. It has an estimated population of about 1.75 million. Its archetype is Queens (both words are positions in a monarchy), and although it shares its name with the muscle car also found in-game, there does not seem to be a relation between the two. The borough is spread across two islands. Seven of its eight districts are located on the Broker/Dukes mainland island, with the eighth being Charge Island in the Humboldt River. Dukes and Broker are the only boroughs in the metropolitan area to share an island. All other boroughs are separated by waters.
Dukes consists of nine, large, heavily-populated neighborhoods and has the second-highest population behind Algonquin.
The character of Dukes varies considerably across its neighborhoods. It has the most green space out of all the boroughs in Liberty City which is particularly concentrated around the districts in the north of the borough such as Meadows Park, and western parts of Francis International Airport.
The income of Dukes itself overall could be described as middle class, as it also could be considered the most suburban out of all four boroughs. The main urbanized district of the borough is East Island City which is centered around the Dukes Boulevard thoroughfare. It contains both modern business land use. It consists of a Bank of Liberty chain, the National Union of Contemporary Arts and the LC24 Tower in addition to declining industrial areas in the neighborhood's southern reaches and Beechwood City, which also merges with Broker. Charge Island is Dukes' other industrial centered local. Commercial shopping areas are centred around Camden Avenue in Cerveza Heights, where the majority of shopping outlets are independent ethnic businesses, as well as Saratoga Avenue in Willis where there is a Shopping Mall as well as the presence of chain business outlets. Cerveza Heights can be considered the neighborhood of central importance in Dukes, with the presence of the borough's medical and policing services on Livingston Avenue as well as the housing of Huntington Street LTA, an important Subway station providing a crossover interchange between the two loops of the 3/8 Broker Line.
Some parts of Dukes could be considered leafy, quaint and expensive suburban locales. These are mainly focused around Willis, Meadow Hills, Meadows Park. Dukes' only housing projects are the Steinway Projects which are located along Yorktown Avenue in Steinway, a working-class neighborhood.
Like the real-life archetype of Dukes, the borough shows evidence of much multiculturalism. The communities often noted for a strong ethnic identity in Dukes include: Irish/German Steinway, Italian/Hispanic/Chinese Cerveza Heights and Jamaican/Caribbean Willis.
