San Giacomo Apostolo church, Dominican church in Forlì, Italy.

San Giacomo Apostolo is a 13th-century church in southern Forlì, built for the Dominican Order and also known as San Domenico. Its interior was rebuilt between 1715 and 1719 to a design attributed to Giuseppe Merenda, in a light late-Baroque style. The complex includes two cloisters and a chapter house, restored in the first half of the 16th century. After the roof collapsed in 1978, restoration made the church usable again from June 2015 as an auditorium.

Dominican friars founded this monastery complex in the 13th century as a center of their religious community. The building underwent substantial structural changes in the 16th century, followed by its interior transformation to Baroque style between 1715 and 1719.

The church is now the Auditorium of the Musei di San Domenico, reopened in June 2015 after restoration and seating over 2,000 people. The complex takes its common name from the Dominican Order, which lived here from the 13th century. Among the friars buried here are Blessed Giacomo Salomoni, venerated on 31 May, and Blessed Marcolino da Forlì, venerated on 2 January.

The church reopened in June 2015 as an auditorium after a long restoration, following the 1978 roof collapse and gutting of the interior. It seats more than 2000 people and forms part of the Musei di San Domenico, so access follows the museum complex rather than a parish schedule.

The Dominican monastery housed several revered figures, including Blessed Giacomo Salomoni and other friars who gained local importance. These religious personalities left behind a tradition of spiritual learning in the community.
