IUE satellite UV spectra of RR Tel covering 1150-3200 A at high and low dispersion through both large and small apertures are reported, and a list of 431 lines is presented which gives measured wavelength, intensity, and full width at half maximum. Over three-quarters of the lines are identified, and a correlation is noted between line width and ionization energy. The lines identified, which include common species ionized from one to four times, are generally resonance, forbidden or semiforbidden lines but also include the recombination lines for C, O and Ne. Many Fe II lines are present. Forbidden line wavelengths are used to define intersystem separations of energy levels in some species. The continuum energy distribution yielded by low dispersion data is not due to a simple recombination of gaseous emission processes and a hot star or accretion disk, but the very high ratio of the energy in the lines to that in the continuum of 2.4 indicates that a high temperature source must be present.
