The National Czech & Slovak Museum & Library (NCSML) is a museum and library of Czech and Slovak history and culture located in Cedar Rapids, Iowa, in the United States. Established in 1974, the museum and library moved to its present site in 1983. The museum and library was severely affected by the Iowa flood of 2008. In 2012, rebuilding and expansion efforts were completed and the NCSML reopened. In 2018, the NCSML became a Smithsonian Affiliate, joining a network of museums, educational institutions, and cultural organizations that share Smithsonian resources. Dr. Cecilia Rokusek serves as the President & CEO of the museum since 2018.
