Energies of the lowest 157 levels belonging to the (1s^2^) 2s ^2^2p^6^, 2s ^2^2p ^5^3l, 2s ^2^2p ^5^4l, 2s ^2^2p ^5^5l, 2s2p ^6^3l, 2s2p ^6^4l and 2s2p ^6^5l configurations of Fe XVII have been calculated using the GRASP code of Dyall et al. (1989, Comput. Phys. Commun., 55, 424). Additionally, radiative rates, oscillator strengths, and line strengths are calculated for all electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transitions among these levels. Comparisons are made with the results already available in the literature, and the accuracy of the data is assessed. Our energy levels are expected to be accurate to better than 1%, whereas results for other parameters are probably accurate to better than 20%.
