Armidale Post Office, Victorian postal building in Beardy Street, Armidale, Australia.

Armidale Post Office is a symmetrical two-storey brick building on a corner site at 158 Beardy Street, with a hipped roof and a projecting single-storey stuccoed arched loggia. A corner addition above the loggia has a Dutch gable and wide brick-arched window openings. The side elevation has cement-rendered banding.

The building was completed in 1880 and replaced an earlier postal service from 1865 that served the growing community. Its design was shaped by the New South Wales Colonial Architect's Office, which influenced many other important public buildings across the region.

The post office remains a working Australia Post branch at the Beardy and Faulkner Streets corner, a junction that anchors Armidale's civic precinct. Its 1897 loggia carries Federation Arts and Crafts lettering in cast cement, and the building is often compared with the loggia of Narrabri Post Office (1879).

The building is easy to locate in town and continues to function as a working post office with its original layout. Visitors can best appreciate the finer architectural features from street level to admire the preservation work undertaken.

The 1897 loggia was compared by heritage assessors to those at the Narrabri (1879) and possibly Richmond (1875) post offices, but Armidale's is set apart by its upper-level additions with a Dutch gable motif. The site may also hold archaeological material relating to earlier uses of the corner.
