The Seyfert galaxy IC 184 and the group around it are described. IDS spectra of IC 184 obtained at the ESO on November 10, 1985 and CCD spectra of IC 184 obtained at Calar Alto on January 17 and February 7, 1987 are analyzed. Seven galaxies are observed in the field around IC 184 and four galaxies form a physically connected group. IC 184 is a bright Seyfert galaxy of type 2 with a visual magnitude of 13.81, an absolute magnitude of -20.5, a dereddened absolute H-alpha luminosity, L(H-alpha), of 2 x 10 to the 20th erg/sec, and an extinction, E(B-V), of about 0.38 mag. It is detected that MCG-01-06-19 and MCG-01-06-20 have prominent absorption lines and weak emission of H-alpha with L(H-alpha) = 9 x 10 to the 38th and 2.4 x 10 to the 39th, respectively; MCG-01-06-22 is an IRAS galaxy with flux values of 0.79 Jy and 1.79 Jy, E(B-V) = 0.93, and L(H-alpha) = 1.1 x 10 to the 41st erg/sec.
