We report the discovery with the IBIS/ISGRI telescope aboard INTEGRAL of a previously unknown hard transient X-ray source IGR J05414-6858. It was detected at the mosaic image accumulated during long observations of the SN1987A field on May 13-22 (~130 ks) and June 6-14 (~400 ks), 2010. The signal-to-noise ratio for the source was 8.8 in the 20-40 keV band. The average flux was equal to 3.5+/-0.4 mCrab that corresponds to the luminosity of 8x1036 erg/s at the LMC distance of 50 kpc.
