Abstract We present spectroscopic observations of extended, off-nuclear broad Hα emission (FWZI~ 4000 km s^-1^) in NGC 4388, a galaxy often classified as a type 2 Seyfert. These features are interpreted as scattered radiation from a Seyfert 1 nucleus that is obscured along our line of sight, possibly by the normal interstellar medium in this galaxy. NGC 4388 strongly resembles NGC 1068, another object with a hidden broad-line region, and may be useful for understanding the relationship between Seyfert 1 and Seyfert 2 galaxies. A scattering origin for the off-nuclear broad emission may be tested by spectropolarimetric observations.
