Santoyo is a municipality located in the province of Palencia, Castile and León, Spain.

The lands within the borders of the current municipality of Santoyo were populated since, at least, classical antiquity. In the Sarnallano moor some material remains of a vaccaean fort can be found. The "Las Quintanas" Roman villa was built in the Late_Roman_Empire, probably in the 4th century - in the 1990s archaeologists discovered amongst its ruins an oven, a hypocaustum, some pottery (both terra sigillata and common) and a well full of debris.

All settlements were abandoned as a consequence of the downfall of the Visigothic Kingdom. The current Santoyo is the result of a resettlement carried out in September 988 (late 10th century) under Fernán de Armentales, a vassal of count García Fernández of Castile. The name of the town itself is most probably derived from the latin Sanctus Ioannes. In the 11th century it was a fortified town, but very scarce remains of the wall have survived.

Built as a romanesque church in the late 12th century, only some windows in the central nave display this initial style. The bell tower (late 13th century) transitions to Gothic. The transept, presbytery and apse are built in late, Flamboyant Gothic (15th century) similar in style to the contemporary parts of Burgos cathedral, by Juan de Arce and Martín de Solórzano. The church's main, southern entrance is covered by a plateresque portico, known as the patriarch's portico, having been funded by Antonio de Rojas Manrique, Patriarch of the West Indies in the 16th century.

Inside the church, the most relevant element is the renaissance reredos, funded by Sebastián Cordero de Nevares. Additionally, a visigothic baptismal font and a plateresque (15th century) walnut wood pulpit can be found. The choir features a baroque organ, built in 1738 by Pedro Merino de la Rosa, carved walnut choir stalls finished in 1750 and a sixteenth-century mudéjar wooden ceiling (1490-1510).

The church has been listed as a Bien de Interés Cultural.
