Sion is a hamlet in the Dutch municipality of Rijswijk.

In 1345, the monastery Sancta Maria in Monte Sion was built in this area.

In the 17th century, an estate was built on the grounds of the former monastery, and in the 19th century, it was divided into small parts and made into farms.

Since 2013, Rijswijk has started construction of several new neighborhoods in the area formerly called Sion.
