Pinus sibirica, or Siberian pine, in the family Pinaceae is a species of pine tree that occurs in Siberia from 58°E in the Ural Mountains east to 126°E in the Stanovoy Range in southern Sakha Republic, and from Igarka at 68°N in the lower Yenisei valley, south to 45°N in central Mongolia.

It differs in having slightly larger cones, and needles with three resin canals instead of two in Swiss pine.

This fungal disease was accidentally introduced from Europe into North America, where it has caused severe mortality in the American native white pines in many areas, notably the closely related whitebark pine.

Siberian pine is of great value for research into hybridisation and genetic modification to develop rust resistance in these species.

Siberian pine, Pinus sibirica, is a popular ornamental tree in parks and large gardens where the climate is cold, such as central Canada, giving steady though not fast growth on a wide range of sites.
