We present echelle spectrophotometry of the Galactic H II region S311. The data have been taken with the Very Large Telescope Ultraviolet-Visual Echelle Spectrograph in the 3100-10400{AA} range. We have measured the intensities of 263 emission lines; 178 are permitted lines of H^0^, D^0^ (deuterium), He^0^, C^0^, C^+^, N^0^, N^+^, O^0^, O^+^, S^+^, Si^0^, Si^+^, Ar^0^ and Fe^0^; some of them are produced by recombination and others mainly by fluorescence.
