La '''Siberia tigro''' (''Panthera tigris altaica''), konata anakxu kiel '''Amura tigro''', estas la plej granda [[subspecio]] de [[tigro]] kiu loĝas ĉefe en la montara regiono [[Siĥote Alin]] kun malgranda populacio ankaŭ en sudokcidento de la [[Ĉemara Regiono]] en la Rusian Malproksima Oriento. En 2005, estis 331–393 plenkreskuloj kaj preskaŭplenkreskuloj en tiu regiono, kun reprodukta plenkreska populacio de ĉirkaŭ 250 individuoj. La populacio estis stabila dum pli ol unu jardeko pro la intensivaj [[Medikonservado|konservismaj]] klopodoj, sed partaj enketoj faritaj post 2005 indikis, ke la rusia tigropopulacio estas malpliiĝanta.<ref name=iucn>{{IUCN |assessors=Miquelle, D., Darman, Y., Seryodkin, I. |year=2011 |id=15956 |taxon=Panthera tigris ssp. altaica |version=2014.1}}</ref>

A comparison of data on body weights of Siberian tigers suggests that in the first half of the 20th century both males and females were in average heavier than post-1970 ones. Siberian tigers weighting up to {{convert|408|kg|lb|abbr=on}} based on reliable reports in the past were common.<ref name=FBW>{{cite book| author=Frasef, A.| year=2012| title=Feline Behaviour and Welfare| publisher=CABI| page=72-77 |isbn=978-1-84593-926-7}}</ref> Siberian tigers captured in a [[Human-wildlife conflict|conflict situation with people]] were usually sick or injured, which may explain their reduced weight.<ref name=Kingofbeasts>Slaght, J.

Results of a [[phylogeographic]] study comparing [[mitochondrial DNA]] from [[Caspian tiger]]s and living tiger subspecies indicate that the common ancestor of the Amur and Caspian subspecies colonized [[Central Asia]] from eastern [[China]] via the [[Gansu]]−[[Silk Road]] corridor from eastern [[China]], and then subsequently traversed [[Siberia]] eastward to establish the Amur tiger population in the Russian Far East.<ref name="driscoll">{{cite journal|author=Driscoll, C.
