The Broadway Avenue Historic District is a historic commercial district in the Broadway–Slavic Village neighborhood of Cleveland, Ohio, in the United States. The commercial district is the historic center of Cleveland's Czech community, and is an excellent example of a district that grew along a streetcar line. The historic district includes 43 buildings constructed between 1888 and 1930, including the Hruby Conservatory of Music and Our Lady of Lourdes Church and School. The commercial district was added to the National Register of Historic Places on October 19, 1988.
