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.
(in the years of World War II) The Czech Chess Union and Czech chess press count all Czech and Czechoslovak titles together, with the resulting ranking as follows: Modr, Břetislav; Veselý, Jiří.
