Valencia de Don Juan (Spanish pronunciation: [baˈlenθja ðe ðoŋ ˈxwan]; Coyanza in Leonese language) is a municipality located in the province of León, Castile and León, Spain.

[2] Originally, Valencia de Don Juan was named Comeniaca and Castrum Covianca in Roman times.

This lasted until the thirteenth century in which it was changed by Valencia de Campos, before renamed to the current name after its first lord and duke, Infante John of Portugal.
