Abstract The region around NGC 4319 has been mapped at 6 and 20 cm with the B configuration of the VLA. The optically luminous 'connection' between the galaxy NGC 4319 and the quasar Markarian 205 was not detected. The nucleus of NGC 4319 was detected at a level that implied a radio luminosity (H(0) = 75) of log L(20) = 19.1. In addition, three resolved radio sources overlap partially or entirely the optical image of the galaxy. The most surprising result is that two of these sources are closely aligned across the nucleus of NGC 4319. The implication of this discovery is that NGC 4319 is an active spiral galaxy exhibiting scaled-down radio galaxy behavior. The brightest soruce in the field (1.6 arcmin NE of NGC 4319) is resolved at 6 cm into a bent, triple-lobe source. The absorption line spectrum of the galaxy associated with this source is found to be z = 0.343.
