The China National Silk Museum (CNSM), near the West Lake, in Hangzhou, is one of the first national-level museums in China and the largest silk museum in the world, covering an area of 50,000 square meters and a building area of 8,000 square meters.

It opened on February 26, 1992, and was extensively refurbished in 2015 - 2016. As the largest specialized museum on textiles in China, the main goal of CNSM is to research and conserve Chinese textile relics. In 2010, it became the home of the Chinese Center for Textile Identification and Conservation (founded in 2000).

The museum has several permanent galleries, including “The Story of Chinese Silk,” “Sericulture and Silk Craftsmanship in China,” a “Textile Conservation Gallery,” and the “Xinyou Archive Center.”

The Chinese Costume Festival, also called the Hanfu Festival, is an annual event that is held at the museum. Every year since 2018, the festival has featured a different theme based on a specific dynasty in Chinese history.
