Argos Hill windmill is a Grade 2* listed building dating from 1835. It is located on top of Argos Hill, near Mayfield, Sussex, and is one of less than 50 post mills remaining in England. It is a fine example of the Sussex tradition in millwrighting and is a landmark for miles around.

The mill ceased working commercially in 1923 and in recent years it has been left to deteriorate. In 2008 Wealden District Council threatened to dismantle the mill. A new body, the Argos Hill Windmill Trust, is currently being set up and will soon be taking responsibility for the mill by leasing it from Wealden District Council.
