The China National Silk Museum (Chinese: 中国丝绸博物馆) is a national-level museum in Hangzhou, Zhejiang province, China.

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 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 China National Silk Museum is a research museum, and has a number of visiting professors and scholars, including Professor Claudio Zanier, Birgitte Samsøe Crawfurd, Suzanne Louise Campion Crawford, Nidaullah Sehrai, Fazal Dad Kaker, and Sanjay Garg.

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 features a different theme based on a specific dynasty in Chinese history. In 2019, the festival won a Chinese Museum Association award for being one of the most innovative in China.

The following is a selection of recent exhibitions. These cover a range of themes, showing the museum's own collections, loaned collections, the museum's scientific and conservation work and archaeological textiles.
