BOABO is a neighborhood in western Broker, Liberty City, in Grand Theft Auto IV. The neighborhood's name is an acronym for "Beneath the Offramp of the Algonquin Bridge Overpass."


North BOABO, as viewed to the south. The Algonquin Bridge is visible, crossing over the riverfront.


It is bordered to the northeast by Stone Street and Valley Forge Avenue (Cerveza Heights); to the north by Hoover Street (East Island City); to the west by the Humboldt River; to the south by Chicory Street (East Hook); and to the south and southeast by Brunner Street (Rotterdam Hill and Downtown).


The neighborhoods and areas of western Broker (i.e. BOABO, East Hook, and Hove Beach west from Iroquois Avenue) lie at sea level along the eastern bank of the Humboldt River - which happens to be at the foot of a rise in the topography of the land east of the riverbank. For this reason, these areas are physically separated from the rest of the borough. As such, western Broker neighborhoods have developed similar aesthetic values and characteristics with each other that are, at the same time, completely distinct from other neighborhoods in Broker. Each area primarily consists of warehouses, docking facilities, and other such industrial structures.

BOABO is experiencing major gentrification, with many of its abandoned industrial facilities having been converted to lofts and condos. However, several warehouses and docks remain, particularly around the southern part of the neighborhood. The effect of gentrification can also be seen in neighboring East Hook, although to a far lesser extent due to its proximity to a working port.

The Angels of Death makes BOABO one of their territories.
