The
Communist Party of Slovakia (, KSS) was a
communist party in
Slovakia. It was formed in March 1939, when the
Slovak Republic was created, as the Slovak branches of the
Communist Party of Czechoslovakia (KSC) were separated from the mother party. When Czechoslovakia was again established as a unified state, the KSS was still a separate party for a while (1945–1948). On 29 September 1948, it was reunited with the
KSC and continued to exist as an "
organizational territorial unit of the KSC on the territory of Slovakia". Its main organ (and thus the main newspaper in Slovakia at the time) was
Pravda.
