  We report the firm discovery of solar-like oscillations in a giant star. We
monitored the star xi Hya (G7III) continuously during one month with the
CORALIE spectrograph attached to the 1.2m Swiss Euler telescope. The 433
high-precision radial-velocity measurements clearly reveal multiple oscillation
frequencies in the range 50 - 130 uHz, corresponding to periods between 2.0 and
5.5 hours. The amplitudes of the strongest modes are slightly smaller than 2
m/s. Current model calculations are compatible with the detected modes.
