San Caprasio is a church in Santa Cruz de la Serós, Jacetania, Spain, in First Romanesque style.

The church is dedicated to St. Caprasius, a 4th-century Gaulish-Roman saint connected to the pilgrims who, during the Middle Ages, ran the Way of Santiago.

The town of Santa Cruz de la Serós was located some 3 km (2 mi) from the route.

In 1089 the diocese of Jaca gave the church to monastery of San Juan de la Peña, which, for some time, converted it into a priorate.

The church has not undergone substantial modifications since its construction in the 11th century, with the exception of the 12th-century bell tower, which is separated from the interior.
