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. A new body, the Argos Hill Windmill Trust Ltd, has been set up and has taken responsibility for the mill by leasing it from Wealden District Council.

A high-profile fundraising campaign has been launched to raise £100K in 2011 towards the first phases of the mill's restoration. The ultimate goal is to restore the mill so that one day the sweeps will be seen turning again over the picturesque hamlet of Argos Hill.
