  We report the identification of 2MASX J032441.19+341045.9 (hereafter 2MASX
J0324+3410) with an appealing object which shows the dual properties of both a
narrow line Seyfert 1 galaxy (NLS1) and a blazar. Its optical spectrum, which
has a H\beta line width about 1600 km s^-1 (FWHM), an [OIII] to H\beta line
ratio ~0.12, and strong FeII emission, clearly fulfills the conventional
definition of NLS1s. On the other hand, 2MASX J0324+3410 also exhibits some
behavior which is characteristic of blazars, including a flat radio spectrum
above 1 GHz, a compact core plus a one-sided jet structure on mas-scale at 8.4
GHz, highly variable fluxes in the radio, optical, and X-ray bands, and a
possible detection of TeV gamma-ray emission. On its optical image, obtained
with the HST WFPC2, the active nucleus is displaced from the center of the host
galaxy, which exhibits an apparent one-armed spiral structure extended to 16
kpc. The remarkable hybrid behavior of this object presents a challenge to
current models of NLS1 galaxies and $\gamma$-ray blazars.
