Ongerup is a town and locality in the Shire of Gnowangerup, Great Southern region of Western Australia.

[4] The area around Ongerup was explored by Surveyor General John Septimus Roe who passed through in 1848.

[5] A local newspaper, The Gnowangerup Star and Tambellup-Ongerup Gazette, was launched on 21 August 1915 with the final edition being printed in 2003.

[13] The town was flooded when 119.4 millimetres (4.70 in) of rain, almost a third of the annual average, fell in one day on 17 February 1955.

It was a shearing competition held on the September Queen's Birthday long weekend with international and national shearers competing in the runup to the Perth Royal Show.

[21] Ongerup featured in an episode of the ABC television series Back Roads that aired on 8 October 2024.

The building survived the closure of the railway and now houses the Ongerup & Needilup District Museum that was opened in 1978.

Surrounding farms mainly produce wheat, barley, canola and wool, while lesser quantities of lupins, oats, alfalfa and other crops are also grown.

The pub, supermarket, cafe, and petrol station were purchased by the community after they had threatened to close.

There is an informative multi-media display area where you can learn more about the conservation of the Malleefowl and local history.
