Heartsease is a small settlement or hamlet in the Welsh district of Radnor and part of the county of Powys. It is close to the border with England and lies near the junction of the two counties of Herefordshire and Shropshire.
Historically, it was part of the Parish of Stanage. For historical population figures see Powys History Project. The hamlet lies on the A4113 road between Knighton and Ludlow and is just a few hundred metres from the River Teme.
Today the settlement is best known as the home of Radnor Hills, a business bottling local spring water.
