Barrack Street is one of two major cross-streets in the central business district of Perth, Western Australia. Together with St Georges Terrace, Wellington Street and William Street it defines the boundary of the main shopping precinct of the central city.
Barrack Street commences at Barrack Street Jetty, and the adjacent Barrack Square. Moving in an uphill direction away from the Swan River, it passes alongside the Supreme Court Gardens and the Stirling Gardens. Crossing St Georges Terrace, Barrack Street then passes alongside the heritage-listed State Treasury Building and the Perth Town Hall. The town hall location was regularly utilised for special occasions – the Centenary of Western Australia celebrations in 1929, and the Royal Visit in 1901 
The street terminates at Wellington Street continuing as Beaufort Street on and over the Barrack Street Bridge which crosses the Midland and Armadale railway lines. The Barrack Street Bridge was constructed in 1894.
Barrack Street existed as a named road as early as 1833. It was named for the military barracks that existed along the alignment, at the corner of St Georges Terrace, in 1829. Construction of the barracks began on 13 August 1829, the day after Governor Stirling declared the foundation of the town of Perth. Soon afterwards, the soldiers' quarters were established, along an alignment that formed the street.
Barrack Street began as a two-way street. In 2010, the section between The Riverside Drive and Esplanade returned to two-way traffic. Further conversion occurred in 2011, the section between Esplanade and St Georges Terrace was changed back to two-way traffic, and on 29 November 2015 the section between St Georges Terrace and Wellington Street was converted.
With the evolution of the properties in the CBD block defined by Barrack Street, Hay Street, Pier Street and St Georges Terrace, Barrack Street has become the western boundary of the Cathedral Square precinct. The renovation and revitalisation of the Perth Town Hall, and Treasury buildings has made the Barrack Street side a pedestrian entry point into the Square..
Barrack Street intersects all the major east-west routes in the Perth CBD. It is the northbound route of State Route 53 through the CBD. William Street, one block over to the west, carries the route southbound.
