Ultraviolet spectra showing emission lines in the 1300--2000 A region have been obtained of 12 Wolf-Rayet stars. In the WN stars, lines of He ii are dominant although N iv lambda1718 and N iii lambda1805 are also present. C iv lambda1549 absorption and a strong continuum in HD 151932, HD 93131, HD 92740 and HD 190918 indicate that all four stars have companions. In the WC stars, lines of C iii and C iv dominate. N iv lambda1718 and N iii lambda1805 emissions are probably present in HD 165763 and HD 156385. The ultraviolet spectra of $gamma$ Vel and theta Mus are dominated by supergiant companions.
