Strathalbyn is a town in South Australia, on the River Angas about 60 kilometres south-east of Adelaide, at the edge of the Adelaide Hills and the Fleurieu Peninsula. The district is the traditional country of the Ngarrindjeri people. The town was founded in 1839, its earliest landholders including Dr Rankine and Donald McLean, and many of its first settlers were of Scottish origin. The town's post office, built in 1911 and 1912, is listed on the Commonwealth Heritage List. Strathalbyn is also a stop on the SteamRanger heritage railway, which runs restored trains down to the coast. Several street scenes for the 1975 film Picnic at Hanging Rock were shot among its nineteenth-century buildings.
