Kupa Synagogue (Polish: Synagoga Kupa) is a 17th-century synagogue in Kraków, Poland. It is located in the former Jewish quarter of Kazimierz developed from a neighborhood earmarked in 1495 by King John I Albert (Polish: Jan I Olbracht) for the Jewish community, which has been transferred from the budding Old Town. Kupa Synagogue serves Kraków's Jewish community as one of the venues for religious ceremonies and cultural festivals, notably the annual Jewish Culture Festival in Kraków.
