Valencia Cathedral, also known as the "Cathedral of the Assumption of Our Lady of Valencia" or simply "Catedral de Valencia" in Spanish, is a Roman Catholic cathedral located in Valencia, Spain. It was built between the 13th and 15th centuries and is known for its mix of architectural styles, which include Romanesque, Gothic, Renaissance, Baroque, and neoclassical elements.

The cathedral's most distinctive feature is its bell tower, known as the "Miguelete," which rises to a height of 207 feet (63 meters) and offers panoramic views of the city. The interior of the cathedral features many notable works of art, including frescoes by Italian Renaissance painter Giambattista Pittoni, a large baroque-style marble sculpture of the Virgen de los Desamparados (Our Lady of the Forsaken), and the Holy Chalice of Valencia, which is believed to be the cup used by Jesus Christ at the Last Supper.

The cathedral also houses a number of chapels, each of which is dedicated to a different saint or religious figure. One of the most popular is the Chapel of the Holy Grail, which contains the Holy Chalice of Valencia. The Holy Chalice is made of agate, gold, and precious stones and is believed by many to be the cup used by Jesus at the Last Supper. It has been kept in the cathedral since the 15th century and is considered one of the most important Christian relics in the world.

The cathedral is also home to a museum that contains a large collection of religious art and artifacts, including paintings, sculptures, and tapestries. Among the highlights of the museum are a 15th-century processional monstrance made of silver and gold, a 16th-century Flemish tapestry depicting the Last Supper, and a collection of paintings by Goya.
