USS Brooklyn (CL-40) was a light cruiser, the lead ship of her class of seven, and the third United States Navy ship to bear its name. Commissioned in 1937, she served in the Atlantic during World War II, as a convoy escort and as fire support for amphibious landings.

Decommissioned in 1947, she was transferred to the Chilean Navy in 1951, where she served for another 40 years. She sank under tow to a scrapyard in 1992.
