Energy levels and radiative rates for transitions among the lowest 97 fine-structure levels belonging to the (1s^2^2s^2^2p^6^) 3s^2^3p^2^, 3s3p^3^, 3s^2^3p3d , 3p^4^, 3s3p^2^3d and 3s^2^3d^2^ configurations of Fe XIII have been calculated using the fully relativistic GRASP code. Additionally, collision strengths for transitions among these levels have been computed using the Dirac Atomic R-matrix Code (DARC) of Norrington & Grant (2004, Comput. Phys. Commun., in prep.). Radiative rates and oscillator strengths are tabulated for all allowed transitions among the 97 fine-structure levels, while collision strengths are reported for some transitions at a few energies above thresholds. Comparisons are made with the available results, and the accuracy of the data is assessed.
