North Sydney Post Office, Heritage post office in North Sydney, Australia.

The North Sydney Post Office at 92–94 Pacific Highway is a two-storey brick building with a four-storey corner tower crowned by a zinc-clad bell dome and detailed stone decoration. It was designed by the Colonial Architect's Office under James Barnet and built from 1885 to 1889 by James Reynolds. Postal rooms occupy the lower floors, while the tower marks the corner of the site.

The building was constructed between 1885 and 1889 by architect James Barnet, replacing an earlier postal station that operated since 1854 under the name St Leonards. The new structure was part of a larger administrative complex reflecting the district's growing importance during this period.

The post office opened on 1 May 1854 under the name St Leonards, the official name of the area until 1890, with G. H. Stevens as first postmaster on an annual salary of £12. He retired in 1870 because of failing health. The office served the lower North Shore and handled mail, telegraph and later telephone traffic.

The location on Pacific Highway is easily accessible and the building remains active as a working post office. Visitors can admire the exterior architecture, though interior access is limited to postal services only.

The first post office here opened on 1 May 1854 under the name St Leonards, the official name of the area until 1890. Its first postmaster, G. H. Stevens, earned £12 a year and retired in 1870 because of failing health. Finding a site for a new office then took the Postmaster General a decade.
