Narrabri Post Office and former Telegraph Office, Telegraph station in Narrabri, Australia.

Narrabri Post Office and former Telegraph Office is a brick building featuring a single-story design with six distinctive arches running across its front facade along Maitland Street. Behind the main structure stands an L-shaped section that once housed residential quarters for postal workers.

Built in 1888 by contractor F.A. King to a design by the NSW Colonial Architect's Office under James Barnet, the post office also served as the town's telegraph office. Flooded in January 1910, it was extended around 1914, when two arches were added to the original four-arched front. A larger telephone exchange was added at the rear in the late 1960s.

The building is also known as the Narrabri Post Office and former Telegraph Office, a name that records its double function. Its arcaded front was originally an open verandah, later filled in to form the public hall, entry porch and a loggia housing post office boxes. The 1888 date plaque sits between the second and third arches.

The building sits directly on Maitland Street and is easy to locate from the street with its striking arched facade clearly visible to passersby. Visitors can examine the exterior details from the public sidewalk without needing special access to appreciate its architectural design.

The date plaque reading 1888 sits between the second and third arches of the Maitland Street facade. The four inset sash windows within the arches have a tuck-pointed, differently coloured arch above each, a detail associated with architect Francis Greenway and repeated here by James Barnet's office.
