An atlas of far-ultraviolet spectra of 45 Galactic OB stars observed with the Far Ultraviolet Spectroscopic Explorer is presented. The atlas covers the wavelength region between 912 and 1185A with an effective spectral resolution of 0.12A. Systematic trends in the morphology and strength of stellar features are discussed. Particular attention is drawn to the variations of the CIII$\lambda$1176, SIV$\lambda\lambda$1063, 1073, and PV$\lambda\lambda$1118, 1128 line profiles as a function of temperature and luminosity class; and the lack of a luminosity dependence associated with OVI$\lambda\lambda$1032, 1038. Numerous interstellar lines are also identified.
