The 2021 Four Nationals Figure Skating Championships were held from 10 to 12 December 2020 in Cieszyn, Poland. It served as the national championships for the Czech Republic, Poland, and Slovakia; traditionally, Hungary has also participated. The three highest-placing skaters from each country formed their national podiums, after the competition results were split. Medals were awarded in men's singles, ladies' singles, pair skating, and ice dance on the senior and junior levels. Due to the COVID-19 pandemic, several skaters training abroad competed virtually via video submissions. The results were among the criteria used by each national federation to determine international assignments.
