Yarrah is a rural locality in the Far North region of South Australia.

[5] A township at Yarrah, located along the railway line, was surveyed in April 1863 and offered for sale on 21 July 1864[6] but was largely unsuccessful.

[9][10] 'The little galvanised-iron church at Yarraville [sic]' is mentioned in the Register newspaper.

[13] The historic Depot Creek Weir is located at Yarrah, and is listed on the South Australian Heritage Register.

The weir dates from 1912 to 1917, when it was built as part of the supply infrastructure for the Port Augusta-Kalgoorlie section of the Trans-Australian Railway; the underlying springs had earlier been used by explorer Edward John Eyre.
