Noncommutative effects are incorporated using the Seiberg-Witten map, and the scattering squared amplitude for the process $e^+e^-\\to t\\bar{t}$ is computed consistently up to second order in the noncommutativity parameter $\\Theta^{\\mu\\nu}$. We derive the total cross-section, the polar and azimuthal angular distributions, and the forward-backward asymmetry, all of which exhibit sensitivity to space-time noncommutativity.
