The Church of San Lucas (Spanish: Iglesia de San Lucas) is located in front of the Bu hill at southeast of the city of Toledo, Castile-La Mancha, Spain. Behind a high wall, attached to the church, was located the old parish cemetery, where it is told that the last Mozarabs of the city were buried.^[1]

Most probably it was built in Mozarab style in the 12th-century,^[2] in the 17th century a Baroque chapel was added to it housing the Virgen de Esperanza.

The church is cited in a poem attributed to St. Ildefonsus, according to which it was erected in 641 by Evancio, a son of Nicholas, who married Blesila and who were the grandfathers of St. Ildefonsus.^[1] This documentary evidence cannot be confirmed and the building could even be a mosque adapted as a Christian church, due to the irregular arrangement of the south wall and the asymmetry of the immediate nave of the epistle.^[1]

The church served one of the parishes of Toledo that had the privilege to maintain the Mozarabic Rite after the Reconquista.
