USS Montpelier (CL-57) was one of 27 United States Navy Cleveland-class light cruisers completed during or shortly after World War II. She was the second US Navy ship to be named for the city of Montpelier, Vermont. Montpelier was commissioned in September 1942 and saw service in several campaigns in the Pacific. Like almost all her sister ships, she was decommissioned shortly after the end of the war, and never saw active service again. Montpelier was scrapped in the early 1960s.

The Cleveland class was a group of light cruisers built for the U.S. Navy during World War II. They were the most numerous class of light cruisers ever built. Fifty-two were ordered, and 36 were completed, 27 as cruisers and nine as light aircraft carriers. They were deactivated within a few years after the end of the war, but six were converted into missile ships, and some of these served into the 1970s. One ship of the class remains as a museum ship.
