The Portland class of heavy cruisers consisted of just a pair of ships built by the United States Navy:

Originally ordered as Northampton class ships in the early 1930s, these cruisers used the same three triple-turret layout for their 8 inch guns, but mounted twice as many 5 inch guns (8 vs 4), and were somewhat heavier. They were redesigned as a result of the original Northampton's being nearly 1,000 tons below the treaty limitations. Since they were built in commercial ship yards, they could not be redesigned to the extent of the follow-on New Orleans class. Instead they were given moderately thicker belt armor and a heavier secondary armament, although they deleted torpedo tubes and the bulbous bow.

The Portlands were superseded by the New Orleans class.
