The Puente de San Martín (English: St Martin's Bridge) is a medieval bridge across the river Tagus in Toledo, Spain.
The Puente de San Martín features five arches, with the largest in the middle having a span of 40 meters. Only very few bridges in the world were that long at the time of its construction.
The bridge was constructed in the late 14th century by archbishop Pedro Tenorio to provide access to the old town from the west, complementing the older Puente de Alcántara linking to the east. Both sides of the bridge were heavily fortified with towers, the more recent dating from the 16th century.
