Swan Barracks, Military heritage complex in central Perth, Australia.

Swan Barracks is a military heritage complex in central Perth consisting of multiple structures built from the 1890s onward. The main building features two stories of limestone with rock-faced finish and Federation Romanesque details, while the compound includes a drill hall, storage facilities, and administrative wings added at different times.

Swan Barracks began as an unnamed drill hall built in 1896, before Australian federation. After federation it served the Australian Army as headquarters of the 5th Military District, an ordnance store was added in 1905, and the complex was named in 1928. It was a military headquarters in the Second World War, and in 1992 its units moved to Leeuwin Barracks in Fremantle. The complex was sold in 1999.

The barracks demonstrate how military institutions shaped the city's development and where the armed forces once operated from. Walking through shows how architecture reflected the importance of defense and order in colonial Perth.

Swan Barracks occupies the block on Francis Street between Museum and Beaufort Streets, a short walk from the Perth Cultural Centre. The complex is a State Registered Place and has passed through hostel and college uses, so the interior is not open as a military museum; the fortress-style administration building and 1905 ordnance store are best seen from the street.

The barracks was named in 1928, more than three decades after its drill hall went up in 1896. The Australian Army stayed through the Cold War, but in 1992 its units moved to Leeuwin Barracks in Fremantle; the complex was sold in 1999 and later housed a backpacker hostel and a private college.
