Old Westmoreland Homestead, Heritage homestead in Nicholson, Queensland, Australia.

Old Westmoreland Homestead is a two-roomed house of hewn sandstone blocks laid with ant bed mortar and fill, measuring 10 by 14 metres including a verandah about 2.3 metres wide. Its hipped roof of early corrugated galvanised iron is fixed with lead-head nails and wire twitches, and the interior is divided by a hardwood frame with single-skin corrugated iron.

Westmoreland Station was taken up in 1881 by Thomas and Robert McIntosh, Robert Philp and William Kirk, covering 640 square miles. Thomas Brassey McIntosh managed the run and built the two-roomed stone house around 1882. The lease passed to the South Australian Mortgage and Land Company by 1887 and to the Bank of Australasia by 1891; after the 1890s drought the run was forfeited in 1897 and stayed unoccupied for about 15 years.

Local residents hold that the stone house is the oldest surviving home in the district. The homestead is now used for storage and outdoor entertainment, and the later kitchen beside it is not heritage-listed.

The homestead stands within the working head station precinct, among lawns south of the main sheds and east of the present homestead, beside dwellings, a cold room, garages and workshops. The stone building itself is now used for storage and outdoor entertainment, so visits depend on the station's permission.

The building was originally part of Westmoreland Station, which occupied a vast property in the bushland. It is the sole residential structure from that era to remain standing today.
