The Oregon City-class was a class of heavy cruisers of the United States Navy.

The Oregon City-class cruisers were a modified version of the previous Baltimore-class design; the main difference was a more compact pyramidal superstructure with single trunked funnel, intended to improve the arcs of fire of the anti-aircraft (AA) guns.

The same type of modification also differentiated the Cleveland and Fargo classes, and to a lesser degree the Atlanta and Juneau classes of light cruisers.

[1] Ten ships were authorized for the class with three being completed and the fourth suspended during construction.

Oregon City was decommissioned after only 22 months of service, one of the shortest active careers of any World War II-era cruiser.
