  We study leptoquark production using polarized $e\gamma$ colliders for the
center of mass energies $\sqrt s=500$~GeV and 1~TeV. We show that using
polarization asymmetries the ten different types of leptoquarks listed by
Buchm\"uller, R\"uckl and Wyler can be distinquished from one another for
leptoquark masses essentially up to the kinematic limit of the respective
colliders. Thus, if a leptoquark were discovered an $e\gamma$ collider could
play a crucial role in determining its origins.
