The INTEGRAL satellite performed a Target of Opportunity observation of the blazar 3C 454.3 following the detection by the AGILE/GRID (ATel #2326) and by the Fermi/LAT (ATel #2328) of a gamma-ray super-flare above 100 MeV on 2009-12-02. Integrating the data from 2009-12-06 16:41 UT to 2009-12-09 07:46 UT, for a net exposure of about 205 ks, we obtain a detection of the blazar with INTEGRAL/IBIS with a flux F(20-40 keV) = 13 mCrab (9.8E-11 erg/cm2/s), and a flux F(40-100 keV) = 16 mCrab (1.5E-10 erg/cm2/s).
