The nearby Seyfert galaxy NGC 7213 has been imaged in H-alpha and HI with theCTIO 1.5 m telescope and with the Australia Telescope Compact Array (ATCA),respectively. Optically NGC 7213 looks undisturbed and relatively featurelessbut the continuum-subtracted H-alpha image shows a 19 kpc long filament locatedapproximately 18.6 kpc from the nucleus. The H-alpha filament could be neutralgas photo-ionized by the active nucleus, as has been suggested for the Seyfertgalaxy NGC 5252, or shock-ionized by a jet interacting with the surrounding HI,as has been suggested for the radio galaxy PKS 2240-41. The HI map reveals NGC7213 to be a highly disturbed system suggesting a past merging event.Comment: 14 pages including 4 figures and 1 table. Figures 1-4 are in jpeg  format; Better quality images can be retrieved in postscript format at  ftp://charon.nmsu.edu/pub/shameed/ ; Accepted for publication in ApJ Letter
