Which Spanish holiday on June 23 features bonfires and fireworks?

The Spanish holiday on June 23 featuring bonfires and fireworks is Noche de San Juan.

Noche de San Juan is Saint John’s Eve, the midsummer celebration held on the evening of June 23, ahead of Saint John the Baptist’s feast day on June 24. It is celebrated across Spain, with especially strong traditions in coastal regions such as Galicia, Catalonia, and the Valencian Community.

Bonfires are the festival’s defining symbol. People gather around fires, often on beaches, and in some places jump over them for good luck. Fireworks, dancing, music, and outdoor parties commonly continue late into the night. Regional foods include coca de Sant Joan, a sweet or savoury festive pastry associated particularly with Catalonia and nearby areas.

The holiday is often linked with older midsummer fire customs, although its Christian name honours Saint John the Baptist. It should not be confused with Nochevieja, which is New Year’s Eve, Nochebuena, Christmas Eve, or Noche de Reyes, the eve of Epiphany. Local names also vary: in Catalan it is Nit de Sant Joan, and in Galician San Xoán.
