Dom Sindikata, Cultural building at Nikola Pašić Square, Belgrade, Serbia

Dom Sindikata is a building on Nikola Pašić Square housing both performance and office spaces across multiple stories. The structure includes a basement, ground floor, mezzanine, and upper levels with rooms designed for various purposes and gatherings.

Architect Branko Petričić designed the building, and construction began in 1947 but was halted by the Tito–Stalin split in 1948. Work resumed in 1951, and the hall opened on 13 June 1957 with Branko Bauer's film Only People as the first screening. It was declared a cultural monument in 2013.

The hall hosted the first FEST in 1971, and Federico Fellini, Roberto Rossellini, Michelangelo Antonioni, Luis Buñuel and Miloš Forman attended. Arthur Rubinstein played on a Steinway & Sons piano that is still kept and used in the hall. Lepa Brena gave 33 consecutive concerts there, and Miroslav Ilić held 29.

The hall closed in July 2017 for a reconstruction that kept the protected exterior and vintage marble floor, banisters and handrails. It reopened on 27 April 2018 with five halls; the Great Hall was reduced to 1,300 seats but remains Belgrade's largest concert hall. A wide passage through the building leads to the Bezistan, the shortest pedestrian route to Terazije.

A large pipe organ was installed in 1957 and remained playable for four decades until 1998, becoming a memorable detail in the building's past. This instrument once contributed significantly to the musical quality of performances held here.
