Using the VINCI instrument installed at the VLT Interferometer (VLTI) the angular diameters of the Alpha Centauri system were measured with a relative precision of 0.2% and 0.6% respectively. From these values we derive linear diameters of D[A] = 1.224 +/- 0.003 Dsun and D[B] = 0.863 +/- 0.005 Dsun. These diameters are in excellent agreement with the models of Thevenin et al. (2002) that use Bouchy & Carrier
