The Barracks Arch is located on the corner of Malcolm and Elder Streets, at the western end of St Georges Terrace in Perth, Western Australia.

Designed by Richard Roach Jewell, the Barracks were originally built from 1863 to 1866 to house the Enrolled Pensioner Force. The Enrolled Pensioner Force came to Australia as guards on convict ships, and were given small land grants in return for part-time guard work. The bulk of convict work moved from Fremantle to Perth in the 1860s, so there was a need to accommodate many Enrolled Pensioners and their families.
