The Czech Republic competed at the 2020 Summer Olympics in Tokyo. Originally scheduled to take place from 24 July to 9 August 2020, the Games were postponed to 23 July to 8 August 2021, because of the COVID-19 pandemic. It was the nation's seventh consecutive appearance at the Summer Olympics after splitting from the former Czechoslovakia.

Several team members, including table tennis player Pavel Širuček, beach volleyball players Ondřej Perušič and Markéta Sluková and road cyclist Michal Schlegel, and delegation members were tested positive for COVID-19 in Tokyo. The anti-epidemic measures were not followed on a charter flight of the Czech team and delegation, the case positivity of unvaccinated tennis doctor (despite wide vaccine availability in the Czech Republic) have caused most controversies.

For the Czech Republic, these were the most successful Olympic Games in terms of medals. Czech athletes broke the previous record from the Olympics in 1996 and 2012 by one silver medal. Josef Dostál became most decorated Summer olympic's athlete in Czech republic's history with 4 medals (1 silver, 3 bronze).
