[5][6] It currently covers a land area of approximately 26.73 km² (10.32 sq mi) and Is bordered by Sutton to the north and east, Frelighsburg to the west, and Richford, Vermont to the south.

This name is probably related to the title held by James Hamilton (1811-1885), Duke of Abercorn.

This title is itself linked to a Scottish village located east of Edinburgh.

The Sutton river runs through the valley, as does Route 139 and the Montreal, Maine and Atlantic Railway.

Located about 105 km from Montréal via Autoroute 10 and near the ski hills of Mount Sutton, Bromont, Jay Peak, Vermont, and Mont Owl's Head, Abercorn is a popular day trip and vacation spot for Montrealers.
