  We show how the seesaw mechanism for neutrino masses can be realized within a
five dimensional (5D) warped geometry framework. Intermediate scale standard
model (SM) singlet neutrino masses, needed to explain the atmospheric and solar
neutrino oscillations, are shown to be proportional to M_Pl\exp((2c-1)\pi kR),
where c denotes the coefficient of the 5D Dirac mass term for the singlet
neutrino which also has a Planck scale Majorana mass localized on the
Planck-brane, and kR~11 in order to resolve the gauge hierarchy problem. The
case with a bulk 5D Majorana mass term for the singlet neutrino is briefly
discussed.
