Mostert's Mill (Afrikaans: Mostert se Meul) is a historic windmill in Mowbray, Cape Town, South Africa. It was built in 1796 and is the oldest surviving complete windmill in South Africa. It was almost completely destroyed by a wildfire on 18 April 2021 but was fully restored by April 2024 and is once more operational and used to grind wheat into whole meal, using the power of the wind. The oldest windmill in South Africa is the De Nieuwe Molen mill in Cape Town, built in 1782.
