I review some of the ideas that have been proposed for the structure of
neutron star interiors, and concentrate on the theoretical arguments for the
existence of superfluidity in neutron stars. I also discuss the implications of
neutron superfluidity and proton superconductivity for the rotational dynamics
of pulsars, and review arguments that have been proposed for observable effects
of superfluidity on the timing history of pulsars and perhaps other neutron
stars. The Lecture notes also include discussions of several features that are
unique to interacting superfluid-superconducting mixtures, as well as the
magnetic structure of quantized vortices in spin-triplet ($^3$P$_2$) neutron
superfluids.
