  Spin-orbit coupling of light has come to the fore in nano-optics and
plasmonics, and is a key ingredient of topological photonics and chiral quantum
optics. We demonstrate a basic tool for incorporating analogous effects into
neutron optics: the generation and detection of neutron beams with coupled spin
and orbital angular momentum. $^3$He neutron spin-filters are used in
conjunction with specifically oriented triangular coils to prepare neutron
beams with lattices of spin-orbit correlations, as demonstrated by their
spin-dependant intensity profiles. These correlations can be tailored to
particular applications, such as neutron studies of topological materials.
