The town is located in what is called the 'Green Heart' of the Netherlands, which is a somewhat less densely populated centre area of the Randstad.The name "Alphen" is probably derived from the name of the Roman fort Albaniana, meaning "settlement at the white water".

In the Roman era, the Oude Rijn was the main branch of the Rhine River and formed the north border of the Roman Empire. Since the rule of Emperor Claudius (41–54 CE), divisions of the Roman army were stationed here. Consequently, several Roman fortifications were located along the Oude Rijn, including castellum Albanianae in the centre of Alphen. The Romans had also built the first bridge over the Oude Rijn. Alphen was therefore an important commercial site in the area until Germanic raids ended that in 240 CE.
