Czech Republic was drawn to compete in the second semi-final of the Eurovision Song Contest which took place on 14 May 2020.

The Czech broadcaster withdrew from the contest between 2010 and 2014 citing reasons such as low viewing figures and poor results for their absence.

[16] According to Eurovision rules, all nations with the exceptions of the host country and the "Big Five" (France, Germany, Italy, Spain and the United Kingdom) are required to qualify from one of two semi-finals in order to compete for the final; the top ten countries from each semi-final progress to the final.

On 28 January 2020, a special allocation draw was held which placed each country into one of the two semi-finals, as well as which half of the show they would perform in.

The Czech Republic was placed into the second semi-final, to be held on 14 May 2020, and was scheduled to perform in the first half of the show.
