Pavia Cathedral (Italian: Duomo di Pavia) is a church in Pavia, Italy, the largest in the city and seat of the Diocese of Pavia. The construction was begun in the 15th century on the site of two pre-existing Romanesque, "twin" cathedrals (Santo Stefano and Santa Maria del Popolo). The cathedral houses the remains of St. Sirus, first Bishop of Pavia, and a thorn from the Crown of Thorns worn by Christ. The marble facing of the exterior was never completed.

Until recently, next to the cathedral stood the Civic Tower (Torre Civica), known in 1330 and enlarged in 1583. It collapsed on March 17, 1989.

The cathedral was begun in 1488, under architect Cristoforo Rocchi, who was soon replaced by Giovanni Antonio Amadeo and Gian Giacomo Dolcebuono. The original project, with a nave and two aisles flanked by semicircular niches and a large central dome, was influenced by Bramante, some details of it later appearing in St. Peter's Basilica in Rome. Leonardo da Vinci is also known to have contributed to the project.

In 1521, the altar area was completed by Gianpietrino Rizzi, a pupil of Da Vinci. By the 17th century, the presbytery had been completed but only in the following century was the tambour built, while the dome itself and the facade had to wait for the 19th century. The dome was designed by Carlo Maciachini and completed in 1885, but partially collapsed the same year. In 1930, construction continued with the two arms of the transept, for which the original plan was followed, although using reinforced concrete (in order to save the remains of the medieval Santa Maria del Popolo). The arms are still missing part of the internal marble decoration.
