The Sibelius was a train run daily by VR between Helsinki, Finland, and St. Petersburg, Russia.

The service began on 31 May 1992 in order to ease congestion on the night service train Repin  [fi; ru] and due to the fall of the Soviet Union, where traffic was increased on the border.

[1] This rail service, along with Repin, was discontinued on 12 December 2010 when it was replaced by the new high speed service Allegro.

[1] Some of the carriages of the train were supposed to be used on regular traffic between Helsinki and Joensuu on IC 5/12 starting on 31 October 2011,[2] but their introduction was delayed until 10 January 2012 due to pending homologation from the Finnish Transport Safety Agency (TraFi).
