Strathaven ⁱ/ˈstreɪvən/ (Gaelic: Strath Aibhne [stra ˈəjnə], meaning: valley of the Avon)^{[citation needed]} is a historic market town in South Lanarkshire, Scotland and is the largest settlement in Avondale. The town was granted a Royal Charter in 1450, making the Town of Strathaven a burgh of barony. The town's principal industry was primarily weaving in the 19th and early 20th centuries, however this declined when faced by competition from Glasgow. The industrial revolution bypassed the town as it had little to offer in the way of natural resources, and thus has grown into more a commuter settlement, however it retains its function as the main service centre for the surrounding area of Avondale. The current population is 7,700.

The town is located on the edge of the valley of the Avon Water, around 6 miles from Hamilton, and 23 miles from Glasgow. The A71, which connects Edinburgh and Kilmarnock passes through the town. In the 2001 census the town had a population of 7,700. Strathaven has one secondary school and three primary schools - Kirklandpark Primary, Wester Overton Primary, and St Patrick's Primary. It also has a grass airfield about two miles to the north west, on Lethame Road.
