The relativistic nuclear recoil corrections to the energy levels of low-lying states of hydrogenlike and high-{ital Z} lithiumlike atoms in all orders in {alpha}{ital Z} are calculated. The calculations are carried out using the {ital B}-spline method for the Dirac equation. For low {ital Z} the results of the calculation are in good agreement with the {alpha}{ital Z}-expansion results. It is found that the nuclear recoil contribution, in addition to Salpeter`s contribution, to the Lamb shift ({ital n}=2) of hydrogen is {minus}1.32(6) kHz. The total nuclear recoil correction to the energy of the (1{ital s}){sup 2}{ital p}{sub 1/2-}(1{ital s}){sup 2}2{ital s} transition in lithiumlike uranium constitutes {minus}0.07 eV and is largely made up of QED contributions.
