Halket Loch (locally pronounced 'Whoreket'), also known as Halkhead or Halketh, was situated in the mid-Ayrshire clayland near Lugton. It is visible as a surface depression in pastureland, sometimes partially flooded, situated in a low lying area close to farms and dwellings of East, North and Middle Halket and Craighead in the Parish of Dunlop, East Ayrshire, Scotland. The loch was natural, sitting in a hollow created by glaciation.
