Bahnhof is a Swedish Internet service provider (ISP) founded in 1994 by Oscar Swartz in Uppsala, Sweden, and is the country's first independent ISP. Today the company is represented in , Gothenburg, Uppsala, Borlänge, and Lund.

used to be hosted in a Bahnhof data center inside the ultra-secure bunker Pionen, which is buried inside the White Mountains in .

Bahnhof was founded in 1994 by Oscar Swartz. It was one of Sweden's first ISPs. The company is publicly traded since December 2007 under the name BAHN-B (Aktietorget). On 11 September 2008, Bahnhof opened a new computer center inside the former civil defence center Pionen in the White Mountains in Stockholm, Sweden.

On 10 March 2005, the Swedish police confiscated four servers placed in the Bahnhof premises, hoping to find copyrighted material. Although these servers were located near Bahnhof's server park (in a network lab area) the company claimed they were not their property since they had been privately purchased by staff. They further presented evidence showing the material on these servers had been planted there by someone hired by Svenska Antipiratbyrån, a Swedish organisation fighting against copyright infringement.

In 2009, Bahnhof generated controversy by failing to store the IP addresses of customers, in order to defeat the Swedish government's new laws on illegal file-sharing, transposing the EU IPRED regulations, which enabled ISPs to retain data longer than the data protection regulations would allow, in order for them to be available on police request.
