Nannup is a town and shire in the South West region of Western Australia, approximately 280 kilometres (174 mi) south of Perth on the Blackwood River at the crossroads of Vasse Highway and Brockman Highway, linking Nannup to most of the Lower South West’s regional centres.
Nannup is the only town within the Shire of Nannup, and has a district high school (1961), telecentre, shire offices, roadhouse, a sporting complex, shopping facilities, accommodation for travellers (hotel/motel, B&Bs, caravan park), and a gemstone museum. The main street has changed little over the years so has considerable heritage value. The Nannup Pineridge Golf Club is 5km north-west of the town in the Cundinup locality.
The timber milling and agriculture (principally beef cattle) dominate the local economy although wine, floriculture and tourism are industries of growing importance. Furniture production and other local timber value adding activities are also a minor employer.
