What is the traditional midsummer night celebration in the Czech Republic called?

The traditional midsummer night celebration in the Czech Republic is called Svatojánská noc.

Svatojánská noc translates as “Saint John’s Night” and refers to customs connected with the eve of Saint John the Baptist’s feast day. The celebration falls near the summer solstice, when many European communities historically marked the seasonal turning point with fires, plant gathering, dancing, and protective rituals.

Czech traditions associated with the night include collecting herbs believed to have special power, lighting fires, and observing folk beliefs about magic and healing. The customs vary by region and are often presented as part of Czech folklore rather than one centrally organized national festival.

The name can be confused with Pálení čarodějnic, the Czech witch-burning festival held on April 30. That spring celebration also uses bonfires, but it is not a midsummer observance. Svatojánská noc specifically belongs to the Saint John and summer-solstice season.
