Roelofarendsveen (Dutch pronunciation: [ruloːˌfaːrəntsˈfeːn]) is a town in the west of the Netherlands.

It is located in the municipality of Kaag en Braassem, South Holland, about 10 km east of Leiden.

The village was first mentioned in 1575 as "Roelifaerts Veen", and means "bog of Roelof Aertszoon" who was probably the peat concession holder.

In 1956, a pumping station was added, and the wind mill now operates on a voluntary basis.

[6] After World War II, the town Roelofarendsveen and the village Oude Wetering have merged to form one built-up area.
