  We have made a clear detection of p-mode oscillations in the nearest
solar-like G2V star $\alpha$ Cen A with the CORALIE spectrograph on the 1.2-m
Swiss telescope at the ESO La Silla Observatory. We report the 5 nights of
observation on this star in May 2001 during which 1260 high precision radial
velocity measurements were obtained. The power spectrum clearly shows several
identifiable peaks between 1.7 and 3 mHz. The average large splitting of 105.7
$\mu$Hz and the amplitude of about 35 cm s$^{-1}$ of these modes are in
agreement with theoretical expectations.
