The article is an extension of the set of papers on seismic tomography of the mantle under the East-European platform (EEP). Three-dimensional P-velocity model of the mantle under the EEP and the Barents-Pechora platform (BPP) is considered in the context of three-dimensional P- velocity model of the mantle under Eurasia. According to velocity characteristics at the depth of 50-500 km the mantle under EEP is integrated with the mantle under BPP. In the layer of seismic lithosphere the mantle under the integrated area of EEP and BPP is specific by high velocities as well as the mantle under the whole territory of the Northern Eurasia except the southern half of the Siberian platform. Velocity characteristics of the mantle under the eastern part of integrated area of EEP + BPP is influenced by mantle velocity area under the West-Siberian platform.
