  We investigate the role of neutron star superfluidity for magnetar
oscillations. Using a plane-wave analysis we estimate the effects of a neutron
superfluid in the elastic crust region. We demonstrate that the superfluid
imprint is likely to be more significant than the effects of the crustal
magnetic field. We also consider the region immediately beneath the crust,
where superfluid neutrons are thought to coexist with a type II proton
superconductor. Since the magnetic field in the latter is carried by an array
of fluxtubes, the dynamics of this region differs from standard
magnetohydrodynamics. We show that the presence of the neutron superfluid
(again) leaves a clear imprint on the oscillations of the system. Taken
together, our estimates show that the superfluid components cannot be ignored
in efforts to carry out "magnetar seismology". This increases the level of
complexity of the modelling problem, but also points to the possibility of
using observations to probe the superfluid nature of supranuclear matter.
