Coupar Angus (/ˈkʊpər/ ⓘ; Gaelic: Cupar Aonghais) lies on the River Isla in the broad and fertile Valley of Strathmore, 4 miles (6 kilometres) south of Blairgowrie. The A94 road from Perth to Forfar runs through the town, and it had a station on the Midland Junction line until 1967.

The town formerly straddled the border between Angus and Perthshire, but it has lain wholly within Perthshire since 1891. It retains the name "Coupar Angus", however, which serves to distinguish it from Cupar in Fife.

In the Middle Ages the Cistercian Coupar Angus Abbey was one of Scotland's most important monasteries, founded by Malcolm IV (1153–65) in the 1160s. Of the abbey, only architectural fragments, preserved in the 19th-century parish church (which is probably on the site of the monastic church), or built into houses and walls throughout the town, survive, along with part of one of its gatehouses.

Strathmore Cycle Hub is a community cycle shop located in Coupar Angus.
