Abies sibirica, the Siberian fir, is a coniferous evergreen tree native to the taiga east of the Volga River and south of 67°40' North latitude in Siberia through Turkestan, northeast Xinjiang, Mongolia and Heilongjiang.

The tree lives in the cold boreal climate on moist soils in mountains or river basins at elevations of 1900–2400 m. It is very shade-tolerant, frost-resistant, and hardy, surviving temperatures down to −50 °C.

Siberian fir, Abies sibirica, grows 30–35 m tall with a trunk diameter of 0.5–1 m at breast height and a conical crown.

They are light green above with two grey-white stomatal bands underneath, and are directed upwards along the stem.

There are two varieties: Abies sibirica is subject to infection from the fungus Delphinella balsameae which was reported from Russia for the first time in 2003.
