We consider the long-time behavior and optimal decay rates of global strong solutions for the isentropic compressible Euler equations with damping in R3in the present paper. When the regular initial data belong to some Sobolev space Hl(R3)∩B˙1,∞−s(R3) with l⩾4 and s∈[0,1], we show that the density of the system converges to its equilibrium state at the rates (1+t)−34−s2in the L2-norm or (1+t)−32−s2in the L∞-norm respectively; the momentum of the system decays at the rates (1+t)−54−s2in the L2-norm or (1+t)−2−s2in the L∞-norm respectively, which are shown to be optimal for the compressible Euler equations with damping.
