It is bordered by Zoetermeer to the north, by Nootdorp to the northwest, by Delfgauw to the southwest, by Rotterdam (specifically Overschie) to the south and by Berkel en Rodenrijs to the east.

Pijnacker was a separate municipality until 2002, when it merged with Nootdorp to form Pijnacker-Nootdorp,[2] which is a part of Greater The Hague.

While it may then seem strange that the two towns would want to merge, they did so preemptively to avoid potential annexing by the cities.

One of the dominant buildings in Pijnacker is H. Joannes de Dooper Catholic church on the main street of town, the Oostlaan.

[3] Though once it was a parish with a full-time priest, the Church of Saint John the Baptist (Pijnacker)[4] is now joined with the Church of Saint Bartholomew (Nootdorp) to form one parish within the "Parish Federation of Oostland" within the Roman Catholic Diocese of Rotterdam.
