We present optical and near-infrared images, H I 21 cm emission maps, optical spectroscopy, and Hubble Space Telescope Space Telescope Imaging Spectrograph ultraviolet spectroscopy of the QSO/galaxy pair SBS 1122+594/IC 691. The QSO sight line lies at a position angle of 27° from the minor axis of the nearby dwarf starburst galaxy IC 691 (cz_gal=1204±3 km/s, L_B∼0.09L^*, current star formation rate=0.08-0.24 h^–2₇₀M_☉/yr) and 33 h^–1₇₀ kpc (6'.6) from its nucleus. We find that IC 691 has an H I mass of M_HI_=(3.6±0.1)x10⁸ M_☉ and a dynamical mass of M_dyn=(3.1±0.5)x10¹⁰ h^–1₇₀M_☉. The UV spectrum of SBS 1122+594 shows a metal-line (Lyα+C IV) absorber near the redshift of IC 691 at cz_abs=1110±30 km/s. Since IC 691 is a dwarf starburst and the SBS 1122+594 sight line lies in the expected location for an outflowing wind, we propose that the best model for producing this metal-line absorber is a starburst wind from IC 691. We place consistent metallicity limits on IC 691 ([Z/Z_☉]~-0.7) and the metal-line absorber ([Z/Z_☉]←0.3). We also find that the galaxy's escape velocity at the absorber location is v_esc=80±10 km/s and derive a wind velocity of v_w=160±50 km/s. Thus, the evidence suggests that IC 691 produces an unbound starburst wind that escapes from its gravitational potential to transport metals and energy to the surrounding intergalactic medium.
