Tot Voordeel en Genoegen is a windmill built in 1798 on the Molendijk 15 in Alphen, Gelderland, in the Netherlands.
It is a large post mill, built above a roundhouse, used for grinding wheat flour.
It is the only windmill in the Netherlands that drives three pairs of millstones.
The mechanism is mostly wooden, since iron was expensive when it was built.
