The Society of Saint Casimir (Lithuanian: Šv. Kazimiero draugija) was a Lithuanian society that published Lithuanian-language books and periodicals, many on Roman Catholic church and faith. Established in 1905, right after the Lithuanian press ban was lifted, the society published a total of about 740 books and several periodicals, including the first full Roman Catholic Bible translation into Lithuanian in six volumes in 1911–1937. From 1918 it operated its own printing press Šviesa. The society was liquidated after Lithuania was occupied by the Soviet Union in June 1940.
