Observations of the central region of M31 were made at 1465 and 4885 MHz with the 1-km configuration of the VLA telescope. It is shown that the M31 central radio source is a nearly spherical distribution of nonthermal synchrotron emission with a 1465 MHz brightness distribution that falls off exponentially from the center with a scale factor of 1.1 arcmin and can be traced to distances of 1 kpc from the nucleus. A triple radio source is found, which is 9 arcmin NE of the nucleus with a position angle of about 70 deg, and which is most likely associated with a background elliptical galaxy coincident in position with the central source in the triplet. The broad structure of the object may be due to a bulge population of many weak supernova remnants or a cosmic ray electron-dominated galactic wind.
