Anglicanism in Spain has its roots in the 16th-century Spanish Reformation. Today it is represented by two Church bodies, namely, the Spanish Reformed Episcopal Church and Church of England's Diocese in Europe.

Protestantism has had a small impact on Spanish life. In the first half of the 16th century, Reformist ideas failed to gain traction in Castile and Aragon. In the second half of the century, the Hispanic Monarchy and the Catholic Church managed to clear the territory from any remaining Protestant hotspot, most notably after the autos-da-fé in Valladolid (1559) and Seville (1560), from then on. 16th-century Inquisition blurred differences between erasmism, iluminismo and protestantism as if they belonged to a common branch.
