Arrilalah is a ghost town in the locality of Longreach in the Longreach Region of Western Queensland, Australia.

[1] The site was originally settled in the 1860s with the name "Forest Grove", but the name was changed to Arrilalah, a word with an uncertain origin, in 1885.

The town began a long decline when the railway bypassed it, instead connecting to the nearby town of Longreach.

[2] Arrilalah Provisional School opened circa 1889 and closed in 1906 due to low attendances.

The local cemetery was rededicated in 2010, and was the site of approximately forty burials.
