Kingoonya is a small settlement in the far north of the Australian state of South Australia. It was established in the early 1900s as a railway support town on the line extending west and played a significant role in the construction of the Trans-Australian Railway. A Kingoonya Post Office first opened around 1884, closed in 1892, reopened in 1915 after the arrival of the railway and closed again in 1982. When railway services were rationalised in the early 1990s, Kingoonya was almost abandoned.
