The analysis of an INTEGRAL AO2 observation of the error contours of theEGRET source 3EG J1621+8203 is presented. The only source found inside theerror contours for energies between 20 and 30 keV at 5 sigma detectionsignificance is the FR I radio galaxy NGC 6251. This supports theidentification of NGC 6251 with 3EG J1621+8203. The observed flux is higher andsofter than observed in the past, but consistent with a variable blazar-likespectral energy distribution.
