Glen Aplin is a rural village on the New England Highway, 14 km south-west of Stanthorpe. It was named after an early mine proprietor, Dyson Aplin.

The Warwick to Stanthorpe railway opened in 1881 and was extended through Glen Aplin to Wallangarra in 1887. At that time Glen Aplin was mainly under open-range grazing, with a few farm selections and orchards. A primary school opened in 1887, but as late as 1901 the post office directory could only record seven farmers and selectors at Glen Aplin. Their number increased to 19 in 1913, but soldier settlement after World War I completely changed local agriculture. In 1924 there were 42 orchardists, 21 farmers and selectors, the Glen Aplin Hostel, a store and a mining dredge. Twenty five years later there were 54 farms recorded, 50 of them fruit orchards. There were also a motor garage, a butcher, a baker and a sawmill, and the Glen Aplin dredge was still mining local waters.

Glen Aplin is part of the Granite Belt country and gourmet tourism. There are four or more local wineries, and others to the south at Ballandean. Visitors have a choice of bed-and-breakfast places and a caravan park. A roadhouse supplies fuel, groceries and meals.
