Beulah, Heritage farmhouse in Gilead, New South Wales, Australia.

Beulah is a colonial farmhouse on Appin Road built with random stone walls and a distinctive double-pitched roof arranged around a central hall. The main house sits within a 90-hectare property that includes formal gardens, native forests, and a timber beam bridge spanning Woodhouse Creek.

It was built between 1835 and 1846 by Cornelius O'Brien and Duncan Cameron as Summer Hill Estate. The property gained its current name Beulah in 1884 during a period of gradual expansion and change in ownership.

The name Beulah comes from the Hebrew for "married", a biblical reference applied to the property in the 1880s. The land itself traces back to four Crown grants promised between 1814 and 1820, including 16 hectares to Irish convict Cornelius Bryan of Clonmel, County Tipperary, transported for life in 1802. Bryan was among the first of a series of Irishmen linked to Beulah to return home to Ireland.

Beulah is a privately owned working farm at 767 Appin Road, Gilead, and is not open to visitors; the house and grounds can only be seen from the public road. The property lies in the Macarthur region on Sydney's outer south-western edge, and the State Heritage Register listing of 2 April 1999 records the farmhouse and its setting rather than any public facility.

The four original land grants that make up Beulah were promised between 1814 and 1820, and the farmhouse stands on portion 78, 16 hectares granted to the Irish convict Cornelius Bryan of Clonmel, County Tipperary, transported for life in 1802. A 1831 re-gazetting of the grant recorded his name as Cornelius Ryan, an error that long misled historians tracing the property's ownership.
