  We present far-ultraviolet spectra of the classical T Tauri star RU Lupi
covering the 912-1710 A spectral range, as observed by the HST/STIS and FUSE
satellites. We use these spectra, which are rich in emission and absorption
lines, to probe both the accreting and outflowing gas. Absorption in the
Ly-alpha profile constrains the extinction to A_V=0.07 mag, which we confirm
with other diagnostics. We estimate a mass accretion rate of
(5\pm2)\times10^{-8}$ M_\odot/yr using the optical-NUV accretion continuum. The
accreting gas is also detected in bright, broad lines of C IV, Si IV, and N V,
which all show complex structures across the line profile. Many other emission
lines, including those of H_2 and Fe II, are pumped by Ly-alpha. RU Lupi's
spectrum varies significantly in the FUV; our STIS observations occurred when
RU Lupi was brighter than several other observations in the FUV, possibly due
to a high mass accretion rate.
