The Sperillen Line (Norwegian: Sperillbanen) is an abandoned railway which ran through Ringerike in Buskerud, Norway.

The rail line had additional stations and stops at Hallingby, Somma, and Ringmoen at the south end of Lake Sperillen.

Bægna went in service from her maiden voyage on 13 October 1868 and continued in traffic until 1929, when it was replaced with a motor ship, DS Spirillen.

In 1921, Parliament voted to build a railway between the Randsfjord Line and a new port at Finsand on Lake Sperillen to connected for the ferry service.

In 1933, passenger service on the rail line was terminated, as was the ferry traffic on Lake Spirillen.
