The Collegio Alberoni is a Roman Catholic seminary located on Via Emilia Parmense #77 in Piacenza, Italy. The complex also includes a prominent art gallery, Galleria Alberoni. Affiliated with the seminary are an seismic and astronomical observatory (founded 1870), a museum of natural sciences, a library, and the parish church of San Lazzaro e San Vincenzo De Paoli.

The institution was endowed by the Cardinal Giulio Alberoni (1664-1742); construction began in 1732, and the seminary opened in 1751. In 1746, during the War of Austrian Succession, the structures of the time were nearly razed. It is now administered by the Congregation of the Mission, also known as Vicentines.

The mission of the seminary as set forth by Alberoni was to provide for the subsidized education of the clerics for the diocese of Piacenza. Among its objectives were an "education in divinity", "virtuous orientation' for which the alumni should demonstrated docility, and a realistic capacity to work for the common good, respect for the property of the college, distance from secularism, and the capacity to disrobe the spirit of the word, and garner those of Christ. Admission was by contest. Studies lasted 8 years and included humanistic disciplines such as philosophy and morals. The institution rapidly adapted to an enlightened education, including scientific methods.

The small art gallery, derived mainly from the collections of the Cardinal Alberoni. The exhibition space was refurbished and modernized in the 1960s by the architect Vittorio Gandolfi. The gallery is open on Sundays from 15:30 to 18:00 during October to June.
