The Czech National Chess Championship (Czech: Mistrovství České republiky v šachu) is the chess competition held to determine the best chess player from the Czech Republic.
First national championships were held every second year, as the championships of Bohemia (within the Austro-Hungarian Empire), between 1905 and 1913, before the founding of independent Czechoslovakia. Afterwards, the independent Czech Republic's championships continued the tradition.
1905–13 – championships of Bohemia
1940–44 – championships of Bohemia and Moravia
1993–present – championships of the Czech Republic
