The Cathedral of Saint Mary of the See (Spanish: Catedral de Santa María de la Sede), better known as Seville Cathedral, is a Roman Catholic cathedral in Seville (Andalusia, Spain). It is the largest Gothic cathedral and the third-largest church in the world.

At the time of its completion in the 16th century, it supplanted the Hagia Sophia as the largest cathedral in the world. Previously, the Hagia Sophia had held the title for almost a thousand years. The cathedral also serves as the burial site of Christopher Columbus. The Archbishop's Palace is located on the northeastern side of the cathedral.
