Kirkby Moor is a poorly defined moorland area in southern Cumbria, England, named after the village of Kirkby-in-Furness, but stretching both sides of the A5092 road, and thus spanning the border of the Lake District National Park. The highest area, to the south of the road, and therefore outside the national park, is named Lowick High Common on Ordnance Survey maps, but "Kirkby Moor" is more commonly but incorrectly used.
